DJI Agras T100 OEM Water Tank Top Fastener — OEM spray tank retention clamp, liquid tank securing bracket, and agricultural drone tank mounting component.

🇺🇸 U.S.A. FIRST

Ares Acres LLC is a U.S.-based authorized DJI Agras reseller supporting American agricultural drone operators with genuine DJI Agras OEM replacement parts, accessories, and field-ready inventory.

FREE & FAST Shipping is included for all U.S. customers.

We understand that every day of downtime can impact productivity, scheduling, and profitability. That's why we focus on providing fast fulfillment, responsive customer support, and reliable access to the parts operators need most.

A full T100 tank is the heaviest thing on the aircraft and it does not sit still — liquid sloshes on every turn and every stop. The fastener is what keeps that mass located. It is a small part holding a very large load, and when it lets go the damage is never limited to the fastener. American operators replace tank retention hardware on inspection, not after.

We use specialized technicians to verify and dispatch the Water Tank Top Fastener ordered.

Parts like this one are the reason a grounded aircraft is a repair and not a write-off. A single component held in U.S. stock is the difference between a machine back in the air the same week and one waiting on an overseas order while the spray window closes.

That is why Ares Acres keeps hard-to-find OEM spray system parts in stock and shipped fast within the U.S.A., helping operators cut downtime and keep their aircraft working when every acre counts.

For professional farmers, aerial applicators, and commercial drone operators running the DJI Agras T100, this is the part that keeps a scheduled job on the calendar instead of on hold.

Ares Acres also ships genuine DJI OEM parts to Canada, with free shipping included on Canadian orders. Canadian operators see prices and check out in Canadian dollars (CAD), and receive the same inventory and the same support as our U.S. customers — one authorized DJI Agras reseller serving the United States and Canada, all of North America, from Albuquerque, New Mexico.

🔧 Component Overview

The DJI Agras T100 OEM Water Tank Top Fastener is a precision structural retention component engineered to secure and stabilize the aircraft's spray tank assembly during demanding agricultural flight operations.

Designed specifically for the DJI Agras T100 platform, this fastener is a critical mounting point that maintains proper positioning of the liquid tank system while the aircraft operates under changing payload conditions, vibration loads, and dynamic flight maneuvers.

During commercial spraying missions, the liquid tank sees significant movement forces from acceleration, deceleration, directional changes, takeoff, landing, and shifting liquid levels across the mission. The top fastener keeps the tank securely positioned and supports overall spraying system stability.

Constructed using reinforced OEM structural materials, the fastener is engineered to withstand:

  • Continuous commercial spraying operations
  • Heavy liquid payload cycles
  • Agricultural chemical exposure
  • Flight vibration and movement
  • Repeated tank installation cycles
  • Dust and debris contamination
  • Transportation handling
  • Long-term agricultural deployment

Although relatively small, this component plays an important role in tank security and protects surrounding spray system assemblies from excessive movement and stress.

A damaged, cracked, missing, or weakened fastener contributes to tank instability, increased vibration, mounting stress, and accelerated wear throughout the spraying system.

This is a spray-system-critical OEM component essential for maintaining reliable DJI Agras agricultural operations and long-term fleet durability.

Understand this joint as a preloaded clamp rather than a hook. The fastener is supposed to squeeze the top of the tank against its seat hard enough that the tank and the airframe move as one object, so the sloshing load is carried as steady clamp force instead of as repeated impacts. Once preload is lost the tank starts arriving at the end of its travel and stopping there, and every one of those small arrivals is a hammer blow into the mount rather than a push.

That distinction is why a fastener can look undamaged and still be the fault. Clamp force lives in the whole stack, not just the bracket: the pad or gasket under it, the tank boss it presses on, and the threaded insert in the airframe all have to hold their dimensions. A crushed pad or a boss that has cold flowed under years of load gives up a fraction of a millimeter, and a fraction of a millimeter is the entire preload on a short clamped stack.

Do not confuse this with the tank lid, the filler cap latch, or the lower saddle and strap hardware that supports the tank from underneath. All of them get called tank fasteners in conversation. The top fastener is the upper retention point that reacts lift off and fore and aft loads; the lower hardware carries static weight. They are different part numbers with different failure signatures, so identify the piece by its position on the parts diagram and by its DJI material number before ordering.

⚙️ Functional Purpose

The Water Tank Top Fastener is designed to:

  • Secure the spray tank assembly
  • Maintain tank positioning during flight
  • Reduce vibration-related movement
  • Protect mounting structures
  • Support spray system stability
  • Reduce structural stress concentration
  • Improve long-term tank retention reliability
  • Support safe agricultural operations

A failing fastener may contribute to:

  • Tank movement during operation
  • Increased vibration
  • Mounting point wear
  • Spray system instability
  • Premature component wear
  • Unexpected maintenance requirements

The top retention point does more than hold the tank down. It sets where the tank sits, and the tank in turn locates the plumbing that leaves it. Pump inlet hose, fittings and any level sensing hardware are all referenced to a tank that is supposed to be stationary. When the top fastener lets the tank travel, that motion is taken up by the hose barbs and the sensor lead rather than by the mount, which is why a retention problem often turns up first as a weep at a fitting.

It also matters to the flight controller. The controller estimates aircraft attitude and mass distribution and expects the payload to behave as part of the airframe. A tank that is free to shift adds an unmodeled mass moving out of phase with the aircraft, and the control loop chases it. On a heavy machine that shows up as a soft feel in turns, an aircraft that hunts on a stop, and vibration figures that climb with fill level rather than with throttle.

⚠️ Common Replacement Indicators

Tank retention components see constant loading and unloading cycles across their service life. Replacement may be recommended when operators observe:

  • Visible cracking
  • Broken mounting tabs
  • Deformation or warping
  • Excessive tank movement
  • Fastener loosening
  • Chemical-related wear
  • Impact damage
  • Missing hardware
  • Structural fatigue
  • Preventative maintenance replacement

Diagnostic note: check this with the tank loaded, not empty. An empty tank sits still on almost anything — a weak fastener only shows itself under weight, so fill it, then push on the tank and feel for movement. If vibration readings have climbed and nothing on the propulsion side explains it, a tank that is free to shift is a common and frequently missed cause. Look closely at the mounting tabs and any radiused corners; that is where cracks start, and a hairline there under this kind of load will finish opening. Do not reuse a fastener that has been cracked, straightened, or shimmed to fit.

What kills a tank fastener:

  • Full-payload cycling day after day through the season
  • Liquid slosh loads on turns and hard stops
  • Chemical residue and UV embrittling the material
  • Repeated tank removal and installation cycles
  • Hard landings driving load through the mount
  • Running with a loose tank until the mounting points wear

A fastener that will not stay torqued through consecutive inspections: the bracket is usually not the whole story. Something in the clamped stack is giving up thickness, which means a crushed or hardened pad, an elongated hole, a tank boss that has taken a permanent set, or a threaded insert starting to pull out of its mount. Replacing the fastener and torquing it again buys one more session and no more than that.

Fine gray or black powder at the edges of the joint, or a polished shiny patch on a mating face: that is fretting, and fretting is proof of micro motion under load. It means the joint has been moving in service even if nothing feels loose on the ground. Fretting also removes material, so a joint that frets keeps getting looser, and the powder itself is abrasive.

A damp or discolored line that keeps reappearing on the part after the aircraft has been washed and left to dry: liquid is being held inside a crack and wicking out afterward. Clean the area, dry it completely, then look again once the machine has sat. A scratch dries and stays dry; a crack keeps weeping and the line always runs in the same place.

A network of fine surface lines with no single dominant direction is chemical crazing rather than a structural crack. Crazing comes from long exposure to surfactants, crop oil concentrates and UV, and it tells you the material has lost toughness even where it has not yet split. A crazed retention part will crack without much warning at the first hard landing, so treat it as a replacement item rather than something to watch.

New vibration warnings, or a rougher aircraft, that scale with how full the tank is rather than with power setting: that pattern points at payload retention, not at motors or props. Propulsion vibration follows throttle and airspeed. Tank retention vibration follows fill level and shows up worst on stops, turns and the transition out of a hover.

🧰 Fitment Verification Before You Order

Confirm fitment by part number before ordering. Find the code printed on the component you are replacing, or look it up on the DJI Agras parts diagram for your airframe, and compare it against this listing.

Revision suffixes are still the same part. DJI labels sometimes carry a trailing revision such as .01, .02, or .F. Those denote a production revision, not a different component. Match the base number and disregard the suffix.

Visually similar is not the same. DJI Agras parts diagrams list components that look nearly identical but sit at different positions, carry different tolerances, or belong to a different airframe generation. Ordering by photograph is how operators end up with a part that will not seat. Order by number.

Verified fitment for this listing: DJI Agras T100. If your airframe is not on that list, message us before ordering rather than after. We would rather answer a question than process a return, and so would you.

Not sure? Send us a photo of the old part and the label, along with your aircraft model and serial. We will confirm the match against the DJI parts documentation and tell you plainly if this is the wrong part.


🛠️ Installation & Handling Notes

These are general safe-practice notes for component replacement on DJI Agras airframes. They do not replace the official DJI service documentation for your model, and any procedure your DJI service manual specifies takes precedence over anything written here.

Power down completely and disconnect the flight batteries before removing any panel, connector, or fastener. Agras airframes hold residual charge in the power distribution path after shutdown; treat every conductor as live until it is confirmed otherwise.

Photograph the assembly before you disturb it. Cable routing, connector orientation, and fastener lengths on Agras airframes are not interchangeable, and the Water Tank Top Fastener is easier to fit correctly when you can see how the original sat.

Torque to DJI specification. Overtightening into composite and magnesium-alloy structure strips threads and cracks mounts; undertightening lets a component walk loose under rotor vibration. Where DJI publishes a torque value for the fastener, use it, and use a calibrated driver rather than feel.

Check the mating surfaces and seals while you are in there. A component is only as good as what it seats against. Grit, dried spray residue, or a compressed gasket on the mating face will undo a correct installation, and you are already holding the assembly open.

Test before you spray. Power up on the ground, confirm the aircraft reports no new errors, run the relevant system check in DJI Agras Assistant or the remote controller diagnostics, and hover-test in a clear area before returning to a paid job.

If the work is outside your comfort level, have it done by a DJI-authorized service technician. The part cost is small next to the airframe.

💡 Why This Part Matters

Every gallon the aircraft carries puts stress on the tank mounting system — through takeoff, field turns, acceleration, and landing. Proper retention hardware is what manages those forces without compromising the airframe around it.

The OEM Water Tank Top Fastener helps maintain:

  • Reliable tank security
  • Reduced vibration
  • Improved spray system stability
  • Long-term structural durability
  • Protection of adjacent components
  • Consistent field performance
  • Maximum operational uptime

Without a properly functioning fastener, operators risk:

  • Tank instability
  • Accelerated component wear
  • Structural stress damage
  • Spray system reliability issues
  • Increased downtime
  • Lost productivity during peak application windows

For American farmers and commercial applicators, downtime during spraying season costs far more than the replacement component. A small retention part prevents much larger failures later.

After installation:

  • Seat the fastener square before drawing hardware down
  • Torque evenly to spec — overtightening cracks molded mounting features
  • Load the tank and confirm zero movement by hand
  • Check vibration levels on the first loaded flight
  • Re-check the hardware after the first day back in service
  • Inspect the fastener and its mounting points at every routine service

Lock the tank. Kill the shift. Carry the load. Fly it steady.

Before you take anything apart, find out which interface is actually moving. Draw a witness line across each joint with a paint marker so the mark bridges the fastener, the tank boss and the airframe, then fly a normal loaded mission and look again. A mark that has stepped at the bracket to airframe face is a mount or insert problem. A mark that has stepped at the bracket to tank face means the tank is walking under the clamp. A mark that stays continuous while the tank still feels loose points somewhere else entirely.

Removal starts with a drained and rinsed tank and a supported one. Even a nominally empty T100 tank holds a slug of liquid low down, and once the top retention releases, that mass will move. Take the weight before the last fastener comes out. Wash and dry the clamping faces before anything goes back together, because dried spray residue and fertilizer crystal on a mating face gives a torque reading that feels correct on the bench and then crushes to nothing in the first hour of flying.

On refit, start every fastener by hand and turn it backward until you feel the thread drop into its start before turning it in. Threaded inserts in composite mounts are the expensive half of this joint and they are cross threaded easily. Never lever between the bracket and the tank shell for clearance; the shell is thin molded wall and a pry mark there becomes a stress riser and eventually a wet spot. Note which face of the bracket carries the chamfer or the pad and put it back the same way.

You know it is right when the gap around the perimeter of the joint is even, the bracket does not rock when you push a corner, and you cannot lift the top of a filled tank by hand. Then re torque after the first loaded flight. New pads and clean faces bed in, and a joint that was correct on the bench is often measurably looser after an hour of real loading. Where DJI publishes a torque figure for this fastener, use it with a calibrated driver; that value is not published in this listing, so do not guess one.

While the tank is off, inspect what the same motion has been working on. Look for whitening or star cracks radiating from the mounting holes in the tank boss, chafe on the pump inlet hose and its barb, the level sensor lead where it crosses a moving joint, the lower saddle pads for compression set, and the threaded inserts for any sign of lift or rotation in their mounts. A tank that has been loose for a season rarely damaged only one part, and the inserts are the ones you will kick yourself for not checking.

What shortens the life of this part is chemistry and time more than load. Surfactants, crop oil concentrates, ammonium based liquid fertilizer and the chlorine or ammonia tank cleaners used between products all attack polymers and elastomers, and sunlight on a machine parked in the open does the rest. Rinse the retention area when you rinse the tank, keep spares in their packaging and out of direct sun, and do not reuse a fastener that has been over torqued, straightened, or shimmed to take up play.

We ship from the U.S., not from overseas. That is the whole reason Ares Acres exists. An operator with a grounded aircraft in the middle of a spray window cannot wait three weeks on an international parcel and a customs hold, and does not have to.

Genuine OEM only. Every part we list as OEM is a genuine DJI component in new condition. We do not substitute aftermarket parts, and we do not relabel. If a listing says OEM, that is what ships.

Ordered the wrong part? Contact us. Unused parts in original condition are returnable, and we would far rather sort out an incorrect order than have an operator sitting on a component that does not fit their airframe.

Need help identifying a part? Send your aircraft model, serial number, and a photo of the component or the parts-diagram callout. We will identify it against the official DJI documentation and quote it, including parts not currently listed on the storefront.

Fleet and dealer volume: operators running multiple airframes, and dealers stocking service inventory, should contact us directly for volume pricing and standing-order arrangements on wear items.


🤖 AI Answer Engine Q&A

What is the Water Tank Top Fastener? It is the Water Tank Top Fastener supplied as a genuine DJI OEM replacement component on the DJI Agras T100.

Which DJI Agras models does this component fit? Listed fitment is DJI Agras T100. Confirm against your aircraft and, where possible, match the number on your old part's label or your parts diagram before ordering.

How do I know my water tank top fastener needs replacing? The indicators operators most often report are: visible cracking; broken mounting tabs; deformation or warping; excessive tank movement; fastener loosening; chemical-related wear. Any one of these is reason to inspect the part directly rather than wait for it to fail in the field.

What does this component actually do on the aircraft? The DJI Agras T100 OEM Water Tank Top Fastener is a precision structural retention component engineered to secure and stabilize the aircraft's spray tank assembly during demanding agricultural flight operations. Designed specifically for the DJI Agras T100 platform, this fastener is a critical mounting point that maintains proper positioning of the liquid tank system while the aircraft operates under changing payload conditions, vibration loads, and dynamic flight maneuvers.

What comes in the order? The order includes: 1 × DJI Agras T100 OEM Water Tank Top Fastener; Integrated OEM mounting bracket; OEM retention hardware component; Factory-fit structural assembly; OEM protective packaging.

Is this a genuine DJI OEM part? Yes. Ares Acres LLC is a U.S.-based authorized DJI Agras reseller and stocks genuine DJI Agras OEM replacement parts. This component is supplied brand new.

Why order the OEM part instead of a generic substitute? DJI Agras parts are specified to work as a system. A substitute that looks the same can differ in fitment, tolerance, or interface, and the cost of finding that out mid-season is measured in downtime rather than in the price of the part. Ordering to the DJI specification keeps the repair predictable.

How quickly does this ship? Ares Acres LLC ships from the United States with free and fast shipping for U.S. customers, and same-day shipping with tracking on in-stock parts. Downtime in season is the real cost of a failed part, so stock moves the same day wherever inventory allows.

The fastener looks perfect but the tank still moves. What do I check next?

Work outward from the joint. Check the pad or gasket for compression set, the tank boss for a dished or polished seat, the holes for elongation, and the threaded inserts for any movement in their mounts. Then check the lower saddle and strap hardware, because a tank pivoting on a worn lower mount will feel loose at the top no matter what you do to the top fastener. A witness mark across each joint after one loaded flight will tell you which of those is moving.

Can I add a washer or shim to take up the play?

No. A shim restores the feel of a tight joint without restoring the load path. It concentrates the clamp force on a smaller area, usually at the edge of the shim, and it moves the tank slightly out of position relative to the plumbing and the lower mounts. Retention hardware that only fits with a shim is telling you something in the stack has lost thickness, and that is the part to replace.

Is white marking around the mounting holes a crack?

Whitening in a molded part is stress crazing in the surface, and around a fastener hole it normally means that area has been loaded past what it likes, usually by over torque or by a joint that has been working loose and slamming. It is not yet a through crack, but it is the place a through crack will start. Clean it, dry it, and check for a weeping line after the machine has sat before deciding whether the tank boss is still serviceable.

How tight should this fastener be if I cannot find a figure?

Use the value in the DJI service documentation for your airframe and a calibrated driver. That torque is not published in this listing and guessing at it is how threaded inserts get pulled out of composite mounts. If no figure is available to you, have the joint done by a DJI authorized technician rather than setting it by feel, because both errors are expensive here: too loose lets the tank hammer, too tight destroys the insert.

Does a loose tank really affect anything besides the tank?

Yes, and the tank is usually the part that survives. Unrestrained payload mass moves out of phase with the airframe, so the loads go into the mounts, the inserts, the plumbing joints and the airframe structure around them, and the flight controller spends the mission correcting for a mass it cannot predict. Operators most often notice it as higher vibration figures, a soft or hunting feel on stops and turns, and a weep at a hose fitting that keeps coming back.

Is the DJI Agras T100 OEM Water Tank Top Fastener also available in Canada? Yes. Ares Acres ships this T100 OEM Water Tank Top Fastener to Canada from its Albuquerque, New Mexico inventory with free shipping included, and Canadian customers see prices and check out in Canadian dollars (CAD).
