DJI Agras T100 OEM Button-Mouth Torsion Spring — OEM folding mechanism spring, aircraft locking tension component, and agricultural drone structural retention spring.
🇺🇸 U.S.A. FIRST
Springs are the parts nobody stocks and everybody eventually needs. This one holds a lock closed — and a lock that has gone soft does not fail on the bench, it fails somewhere between the shop and the field. It costs almost nothing and it will ground an aircraft just as completely as a motor. American operators keep a few in the case.

🔧 Component Overview
The DJI Agras T100 OEM Button-Mouth Torsion Spring is a precision-engineered mechanical spring designed to provide controlled tension and retention force within the aircraft's folding and locking assemblies.
Built specifically for the DJI Agras T100 platform, this spring maintains proper tension, structural positioning, and reliable operation of components that depend on spring-loaded movement and secure locking action.
Agricultural drones live on deployment cycles. Every transport, unfolding sequence, maintenance procedure, and field setup puts repeated stress on the aircraft's mechanical systems — and this spring is what keeps those systems returning to the same position every time.
Manufactured from high-strength spring steel and engineered for repetitive mechanical loading, this OEM component is designed to withstand:
- Continuous folding cycles
- Daily field deployment
- Aircraft transportation
- Vibration exposure
- High-hour spraying operations
- Mechanical stress loading
- Dust and debris exposure
- Long-term commercial use
Springs fatigue. That is not a defect, it is physics — repeated loading gradually reduces tension, and reduced tension means poor locking performance, excessive movement, and accelerated wear on everything the lock was holding.
This is a mechanical-system-critical OEM component that supports long-term aircraft reliability and structural integrity.
⚙️ Functional Purpose
The Button-Mouth Torsion Spring is designed to:
- Maintain proper locking tension
- Support folding mechanism operation
- Improve component retention
- Reduce unwanted movement
- Maintain structural stability
- Support safe aircraft transport
- Improve deployment consistency
- Reduce mechanical wear on adjoining parts
⚠️ Common Replacement Indicators
- Reduced spring tension
- Weak or inconsistent locking performance
- Loose folding assemblies
- Excessive component movement
- Spring deformation or set
- Corrosion on spring surfaces
- Visible cracking
- Broken spring coils
- Increased vibration
- Preventative maintenance replacement
Diagnostic note: a lock that has to be helped closed is already telling you the spring has taken a set. Cycle the mechanism and compare it to a known-good position on the same aircraft — the one that feels softer or does not snap home is the one to change, and side-to-side comparison finds this faster than any single-side inspection. Do not stretch or bend a tired spring back into shape; spring steel that has yielded will not hold the new geometry, and you will be doing it again shortly. Corrosion is a replacement condition on its own, because a pitted spring cracks at the pit and it does it without warning. Cheap part, hard failure — replace on suspicion, not on breakage.
What kills a torsion spring:
- Thousands of load cycles from folding and deployment
- Corrosion from chemical residue, washdown, and humidity
- Over-travel from forcing a binding mechanism
- Grit in the mechanism increasing working load
- Bending or straightening a fatigued spring to reuse it
- Long-term fatigue at high flight hours

💡 Why This Part Matters
Large agricultural drones depend on hundreds of individual components working together. Small size does not mean small consequence — a weak lock is a structural problem wearing a mechanical disguise.
A weakened spring can contribute to:
- Improper locking performance
- Excessive mechanical movement
- Increased wear on adjoining components
- Transport-related damage
- Reduced structural stability
- Unexpected maintenance requirements
Professional operators understand that many major repairs begin with a small component that got overlooked. Replacing torsion springs proactively is one of the cheapest reliability decisions on the aircraft.
After installation:
- Clean grit out of the mechanism before assembly
- Seat the spring in its factory position and orientation
- Cycle the mechanism fully several times by hand
- Confirm the lock snaps home positively with no assistance
- Verify the assembly holds position through a transport cycle
- Inspect springs for set and corrosion at routine service intervals
Load the spring. Snap the lock. Hold the position. Fly it secure.
