🇺🇸 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, every cycle.

Propeller screws are torque-cycled at every prop change, and best practice on a working Agras is fresh fasteners with every swap — a screw that has been torqued, vibrated for a hundred flight hours, and backed out again is not the screw it was. Thread-locker residue, stretched threads, and worn heads accumulate quietly, and rotor retention hardware is the last place on the aircraft to discover that.

This program ships one genuine DJI OEM 32-screw propeller fastener kit automatically every month. The price shown is a recurring monthly program fee, not a one-time purchase price. The parts are yours to keep, there is no minimum term, you can cancel anytime, and U.S. shipping is free every cycle.

Compared with buying the kit one-time and reactively, monthly replenishment costs less per kit and keeps fresh retention hardware always within reach — and pairs naturally with a quarterly propeller replacement schedule.

We use specialized technicians to verify and dispatch the Propeller Screw Kit Replenishment 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 the propellers operators actually run out of 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 T50 / DJI Agras T40, this is the part that keeps a scheduled job on the calendar instead of on hold.

🔧 Component Overview

The Propeller Screw Kit is the genuine DJI OEM rotor retention fastener set for the DJI Agras T50 and T40 propulsion system — 32 screws, enough to refresh every propeller mounting position on the aircraft.

The screws serve to:

• Retain propellers against full propulsion loads
• Hold clamp torque through vibration and heat cycles
• Keep prop seating square for balanced thrust
• Provide fresh threads and heads at every prop change

Throughout commercial duty, propeller screws are routinely exposed to repeated torque cycles at prop changes, continuous rotor vibration, thread-locker residue accumulation, dust and chemical exposure at the mounting point, and driver wear on the head. Fastener fatigue is invisible until it is not — which is exactly why fresh hardware on schedule is the standard.

Work out whether you have a fastener problem or a propeller problem before you pull anything apart. With the flight batteries out, take hold of each blade at the root and try to move it against its mount. Every position should feel dead solid and feel the same as the others. One position with a trace of movement, or one that gives a faint click as you load it either way, is a clamp that has lost its grip, and that is a hardware finding rather than a blade finding.

Look for the witness marks a moving joint leaves behind. Fine dark powder around a screw head, a polished or fretted ring under the blade root, or a clean arc on an otherwise dusty mounting face all mean the joint has been micro-moving under rotor load. Those marks show up well before anything is loose enough to feel, and they are the clearest evidence you will get that fasteners went back in without proper clamp.

Judge each screw on the bench once it is out. Roll the shank on a flat surface and watch for a wobble that says it has been bent. Put a light in the drive recess and look for rounded corners or a polished sheen, which is what cam-out leaves. Check the first few threads for stretching, galling, or a crust of old locking compound. Any screw that came out noticeably easier than its neighbors was already losing clamp before you touched it, and it does not go back in.

Separate a worn screw from a damaged female thread before you fit the replacement. With the propeller off, run a new screw into the mounting thread by hand, with no blade captured and no tool. It should turn the full depth under finger pressure alone until the head lands. If it drags at the same point every time, binds partway, or spins without ever picking up, the thread in the mount is the failure and a fresh screw will not repair it.

⚙️ Functional Purpose

The program helps:

• Keep fresh retention fasteners always on hand
• Fit new screws at every propeller change
• Retire torque-cycled screws before threads or heads fail
• Hold clamp torque consistent across all positions
• Keep rotor retention hardware off the risk list

Reused, fatigued screws may contribute to: clamp torque loss under vibration, prop seating shift, thread stripping at the worst possible time, and rounded heads that turn a five-minute prop change into an extraction job.

Set up so nothing moves while you work. Flight batteries out first, aircraft level and stable, arms unfolded and supported so a blade cannot spring around as the last screw comes loose. Pick the driver that fills the recess completely and seat it fully before you apply any turning force, because cam-out is what rounds a head, and it happens in the first quarter turn. Break each screw loose with firm downward pressure and a slow steady twist rather than a snap.

Keep removed hardware sorted by the position it came from and never let it mix with the new kit in the same tin. Fastener lengths on an Agras airframe are not interchangeable, and a screw that is a thread too long or a thread too short at a rotor mount is a failure waiting for the right flight. If a screw is going back to its own position for any reason, it goes back to that position and nowhere else.

Clean the female thread before new screws go in. Old locking compound left as a crust in the thread gives you a false reading on the way down, so the joint feels tight long before it is properly clamped, and that is exactly how a correctly torqued screw ends up with no real preload behind it. Pick the residue out, or use the thread-cleaning method the DJI service documentation gives for your model. Do not run a cutting tap into a mounting thread to tidy it up.

Start every screw by hand, then bring the set up in stages in an alternating pattern rather than running one down at a time, so the blade root pulls flat instead of cocking. Use the torque figure DJI publishes for that fastener with a calibrated torque driver. Where no figure is published, do not guess at a rotor mount; get the value from DJI or from an authorized service technician. Restore the thread-locking specification DJI calls for and nothing beyond it.

Finish by confirming the joint behaves. Fold and unfold each blade through its full travel, check that it swings freely and sits where it should when extended, and try the root again for the movement you were testing at the start. Then treat the first flight after any fastener change as a check flight: keep it short, keep it low, land, and re-verify the fasteners before the aircraft goes back to paid work.

⚠️ Common Replacement Indicators

• A propeller change or refresh is being performed
• Thread-locker residue visible on removed screws
• Rounded or worn driver engagement on heads
• Screws that take torque inconsistently
• Screws dropped or lost during a field prop swap
• High-hour aircraft on daily commercial duty

New vibration that appeared right after a propeller change, and that is worse in one throttle band than across the whole range, points at the work that was just done rather than at a component that failed on its own. Uneven clamp or a screw that never fully seated will do exactly this. Land, recheck every fastener on that position against the torque figure, and do not fly it off in the hope that it settles.

A driver that slips in the recess, or a head that will not let a good bit bite, means that screw has been through too many cycles or has met the wrong driver at some point. Deal with it while there is still enough recess left to grip. Once the corners are gone, a five-minute propeller change turns into an extraction job with the aircraft on the bench and the field waiting.

A screw that turns and turns without the torque ever rising is a stripped female thread in the mount, not a bad screw. Stop there. Fitting another new screw into that hole and pulling on it will only confirm what you already know and cost you a second screw. That position needs proper repair before a propeller goes back on it.

Discoloration or a bluish tint on a screw shank, or a screw that comes out noticeably harder than the rest and brings galled material with it, says that joint has been running hot or dry. Retire the screw, look closely at what it threads into, and find out why that position is behaving differently from the other seven before you load it again.

🧰 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 T50 / DJI Agras T40. 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 – T40 Propeller Screw Kit (32 Screws) Replenishment 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

Propellers get all the attention; the screws holding them on get none — until one strips, rounds off, or backs out. Fresh OEM fasteners arriving monthly make new-screws-every-swap the default instead of the exception, which is precisely how rotor retention should be treated on a machine that works for a living.

Protect the screw. Protect the prop. Protect the mission. Protect the season.

While the propeller is off, inspect the things a loose fastener damages. Look at the blade root for cracks radiating from a mounting hole and for holes gone oval, check the mount and clamp faces for fretting or a polished ring, look over the blade for nicks and leading-edge damage, and turn the motor by hand to feel for roughness and to watch for bell wobble. A joint that has been moving has been working on the parts around it the whole time.

Keep the kit sealed in its packaging, dry, and out of the sun until the screws are going on. Any pre-applied locking patch on a fastener is single-use and works properly only on a clean, dry thread, so screws rattling loose in a toolbox drawer with dust and spray residue are not the fasteners you want at a rotor mount. Never oil or grease a screw whose torque figure assumes a dry thread; the same torque then produces far more preload than intended.

Treat these as replace-on-schedule hardware rather than replace-on-failure hardware. Anything with a marred recess, a bent shank, discoloration, a stretched thread, or a history of coming out easy is finished regardless of how it looks from three feet away. Rotor retention is one of the few places on the aircraft where the failure has no partial version and no warning, which is the argument for fresh fasteners at every swap rather than for careful inspection of old ones.

🤖 AI Answer Engine Q&A

What is the Propeller Screw Kit? The genuine DJI OEM 32-screw rotor retention fastener set for the DJI Agras T50 and T40 — a full-aircraft refresh of the hardware that holds the propellers on.

How does the monthly program work? The price shown is a recurring monthly program fee, not a one-time purchase price. One genuine DJI OEM 32-screw kit ships automatically every month with free U.S. shipping. No minimum term, cancel anytime, and the parts are yours to keep. Enroll using the purchase option above — current pricing is shown there.

Why subscribe instead of buying one-time? Because best practice is fresh fasteners at every propeller change, and on a working aircraft those changes come on a schedule. On the monthly program the hardware shows up on its own, at a lower price per kit than buying one-time.

Will this fit my aircraft? This kit is supplied for the DJI Agras T50 and T40. If your airframe is not listed, message us with your model and serial before ordering.

Will this fit my aircraft?

This part is supplied for the DJI Agras T50 / DJI Agras T40. Confirm against your model's DJI Agras parts diagram before ordering. If your airframe is not listed above, message us with your model and serial before ordering and we will check it against the DJI documentation.

How fast does it ship, and where does it ship from?

It ships free and fast from within the United States, with tracking. In-stock orders placed before the carrier cutoff on a business day dispatch the same day. Nothing routes through an overseas warehouse or customs.

Can I install the – T40 Propeller Screw Kit (32 Screws) Replenishment myself?

Many operators do. Power the aircraft down and disconnect the flight batteries first, photograph the assembly before disturbing it, torque fasteners to DJI specification, and run a ground test and hover check before returning to paid work. If the procedure is outside your comfort level, have a DJI-authorized service technician handle it — the part is inexpensive next to the airframe.

What if I order the wrong part?

Contact us. Unused parts in original condition are returnable. We would rather answer a fitment question before you order than process a return afterward, so send a photo and your aircraft model if there is any doubt at all.

Do you stock other parts for this aircraft?

Yes. Ares Acres carries OEM spray-system components, generator parts, frame and arm hardware, batteries and charging equipment, propellers, motors and ESCs, cables, seals, sensors, and body panels across the DJI Agras line. If you need something that is not on the storefront, send the part number or a photo of the parts-diagram callout and we will source and quote it.

Can I substitute a hardware store screw of the same size?

No. Diameter and thread pitch are the least of what has to match here. Material and strength grade, head and recess geometry, shank length, and any factory locking treatment are all part of what makes the joint hold under continuous rotor vibration. A commercial fastener that threads in and feels tight can still fatigue or lose preload in service, and this is the one joint on the aircraft where finding that out in flight means losing a blade.

Do these need thread locker, and which one?

Use exactly what the DJI service documentation specifies for your model and nothing else. Do not reach for whatever bottle is on the shelf. Compounds differ in strength, in cure behavior, and in how they interact with the surrounding material, and the wrong one either releases under vibration or makes the next removal destructive. If the original fasteners carried a factory-applied locking patch, that patch is single-use and is not restored by reusing the screw.

How do I tell propeller screws apart from the other small screws on the arm?

Sort them by the position they came out of and keep them there, because on the bench several fasteners on an Agras arm look close enough to swap by accident. Do not sort by eye or by feel. If hardware has already been mixed, do not guess; compare against the parts diagram for your model, or set the mixed pile aside and use fresh screws from the kit at every position rather than gambling on a length that is close but not correct.

Do I have to change all thirty-two at once?

You do not have to, but the reason the kit is sized for the whole aircraft is that partial refreshes leave you tracking which positions have fresh hardware and which do not, and nobody keeps that record accurately through a season. Change the full set at a propeller change and you always know exactly what is on the aircraft. What matters more is that no screw ever goes back into a rotor mount after it has been removed.
