🔧 Component Overview

The DJI Agras T100 OEM Screw M40-HC01400140-070039-0003-Y is the DJI-specification fastener used in the weight sensing system of the DJI Agras T100 — weighing the payload in real time so the aircraft knows exactly what it is carrying depends on hardware that stays torqued.

Weighing the payload in real time so the aircraft knows exactly what it is carrying is the job description for the weight sensing system, and this component is part of how it gets done. The T100 is a working machine — it earns its keep in fill-and-fly cycles, not hangar hours — and every component in the weight sensing system is sized, shaped, and specified around that duty. On the official parts diagram it sits alongside Weight Sensor Signal Cable, Front Weight Sensor Module, Damping Rubber Pad.

Ignore a failing screw m40-hc01400140-070039-0003-y and the bill compounds: downtime in the middle of an application window, collateral wear on the parts around it, and jobs that slip to a competitor while the aircraft sits. Replacing it costs a part; not replacing it costs acres. That trade only runs one direction.

For professional farmers, aerial applicators, and commercial drone operators, this component is how the weight sensing system stays field-ready instead of becoming the reason the aircraft sits.

This is a working part on a working aircraft.

The T100 works brutally hard for its living, including:

• Weighing the payload in real time so the aircraft knows exactly what it is carrying
• Dawn-to-dusk spray campaigns during narrow application windows
• Repeated fill-fly-return cycles with minutes on the ground between loads
• Full-payload takeoffs from field edges, dozens of times per day
• Chemical exposure from fungicides, herbicides, insecticides, and foliar fertilizers
• Pressure-washer rinse-downs at the end of every spray day
• Vibration from eight propulsion motors running at working power
• Transport bouncing on trailers and truck beds between fields
• Temperature swings from cold morning starts to full-sun afternoons

What attacks this component in the field:

• Vibration constantly working against preload
• Torque cycles from repeated maintenance disassembly
• Chemical exposure attacking coatings
• Washdown water reaching threads
• Thermal expansion cycles between day and night operation
• Load reversals through the joint every flight
• Cross-threading and tool damage during field repairs
• Corrosion from fertilizer-laden moisture

That duty cycle is exactly what retires this component. None of these stresses is dramatic on its own — the accumulation is what does it. This is why airframe fasteners are inspection items every time the weight sensing system is opened up, and why operators who run hard keep spares on the shelf.

A healthy screw m40-hc01400140-070039-0003-y delivers:

• Factory-correct fit in the weight sensing system — no modification, no adaptation
• Exact OEM behavior the surrounding components were engineered around
• Restored function you can verify on the first post-repair check
• Correct preload and retention at the joint
• One less known-weak point flying through your application window
• Confidence that the repair is done, not patched
• A maintenance log entry with a real DJI part number behind it
• Full compatibility with the parts around it — because it is the part the diagram calls for

Stock the screw m40-hc01400140-070039-0003-y before the season does its work, and the weight sensing system never becomes the reason the aircraft sits.

⚙️ Functional Purpose

The screw m40-hc01400140-070039-0003-y is designed to do one job in the weight sensing system and do it to specification: weighing the payload in real time so the aircraft knows exactly what it is carrying.

The component:

• Serves the weight sensing system of the DJI Agras T100 exactly as the factory intends
• Supports weighing the payload in real time so the aircraft knows exactly what it is carrying
• Maintains the tolerances and interfaces the surrounding parts depend on
• Withstands the chemical, vibration, and washdown environment of agricultural work
• Holds its torque and preload through vibration
• Keeps failure modes visible and diagnosable instead of mysterious
• Restores factory behavior immediately upon correct installation
• Protects the more expensive components it works alongside
• Carries the exact DJI specification for its position
• Supports safe, predictable operation under full payload
• Eliminates the guesswork of near-fit substitutes
• Keeps the aircraft inside its designed maintenance program
• Holds up across a full season of professional duty

Function on the T100 is a chain: payload measurement system performance depends on the weight sensing system, and the weight sensing system depends on every part in it holding specification. This component is one link in that chain — and chains fail at the worn link, not the average one.

That is why the platform's maintenance philosophy is inspection and renewal, not run-to-failure. The operators with the best uptime records are not the ones with the newest aircraft — they are the ones who replace parts like this when inspection says so, on their own schedule instead of the failure's.

A failing screw m40-hc01400140-070039-0003-y costs you:

• Downtime in the middle of an application window — the most expensive hours in agriculture
• Acres not covered while the aircraft waits on a part
• Collateral wear on the components around the failing one
• Diagnostic hours chasing symptoms instead of causes
• Rework when a temporary fix lets go mid-job
• Customer trust when scheduled work slips
• Higher repair bills the longer the fault runs
• Risk exposure every flight the fault remains aboard
• Resale value on an airframe with deferred maintenance

Fix it on your schedule, not the failure's.

⚠️ Common Replacement Indicators

• Rounded, stripped, or damaged drive recess
• Visible corrosion on head or threads
• Fastener found loose at inspection
• Missing fastener discovered at a walkaround
• Thread damage in the mating part from a failing fastener
• Fretting marks or movement witness at the joint
• Fastener replaced with a wrong-spec substitute during a field fix
• Torque loss on re-check after flights
• Coating worn through and surface rust starting
• Head cracked or deformed from over-torque
• Vibration loosening recurring at the same position
• Any fastener removed more than a few times — replace, not reuse

What kills airframe fasteners: the compounding of ordinary duty. Chemical exposure attacks materials, vibration works at every interface, UV ages every exposed surface, and washdowns drive water at every seam — repeated across hundreds of cycles per season. Add the occasional hard landing or transport knock and the result is predictable: the part that was fine in spring is the failure point by late season.

Replacement and verification: Replacement is a standard shop task on the T100: open access to the weight sensing system, document connections and hardware positions, swap the screw m40-hc01400140-070039-0003-y for the OEM unit, and reassemble with attention to seating, routing, and torque. Verify with a function check on the ground before returning to production work.

Confirm before you order: this is DJI part YC.ST.LL000013. Check the label on your old screw m40-hc01400140-070039-0003-y or the position in your official parts diagram and match the number — revision suffixes like .01 or .F on a label are the same part.

💡 Why This Part Matters

Every acre the T100 covers depends on the weight sensing system doing its job — and the weight sensing system depends on parts exactly like this one.

The economics are simple. The DJI Agras T100 exists to cover ground during windows that do not wait — and every hour it sits, the work either doesn't happen or happens on someone else's schedule. A failed screw m40-hc01400140-070039-0003-y is rarely expensive because of what the part costs; it is expensive because of when it fails. Parts fail during use, and use happens during the season.

That is the case for OEM and the case for stocking ahead. The OEM component fits the first time, behaves the way the platform expects, and carries the exact specification the payload measurement system was engineered around — DJI material number YC.ST.LL000013. No adaptation, no surprises, no second teardown to undo a near-fit part.

This component delivers:

• Factory-correct fit in the weight sensing system — no modification, no adaptation
• Exact OEM behavior the surrounding components were engineered around
• Restored function you can verify on the first post-repair check
• Correct preload and retention at the joint
• One less known-weak point flying through your application window
• Confidence that the repair is done, not patched
• A maintenance log entry with a real DJI part number behind it
• Full compatibility with the parts around it — because it is the part the diagram calls for

Running a compromised screw m40-hc01400140-070039-0003-y, operators risk:

• Mid-job failure during an application window
• Collateral damage to surrounding components
• Progressive damage that turns a cheap fix into an expensive one
• Alignment and fit problems spreading to adjacent parts
• Unplanned grounding with the fleet committed to jobs
• Warranty and service complications from improvised fixes
• Higher lifetime cost from deferred maintenance
• An aircraft that cannot be trusted at full payload

Check the torque. Match the spec. Replace, don't reuse. Keep it tight.
