EFT Arm Lock Cap φ40/4pcs Compatible with E416P/E616P/E410P 40mm
The EFT Arm Lock Cap φ40 is a precision-engineered locking mechanism designed for agricultural drone arm assemblies, specifically compatible with EFT E416P, E616P, and E410P models. This component serves as a critical retention device that secures the drone's arm structure during flight operations and transport, preventing accidental arm separation or misalignment. Professional drone operators and agricultural spray system technicians rely on these caps to maintain structural integrity during high-speed maneuvers and payload delivery operations in field spraying applications.
Product Overview
The EFT Arm Lock Cap operates on a threaded locking mechanism that provides positive mechanical engagement with the arm mounting interface. The 40mm diameter design ensures optimal load distribution across the arm joint, while the four-piece set provides redundancy for multi-arm drone configurations. The cap features precision-machined threads with anti-corrosion coating, enabling secure fastening that withstands vibration, thermal cycling, and exposure to agricultural chemicals commonly used in spray operations. The locking mechanism prevents micro-movements that could lead to fatigue failure in the arm structure during extended flight missions.
This component is manufactured to OEM specifications for EFT drone platforms, ensuring perfect fitment and compatibility with existing arm assemblies. The robust construction accommodates the dynamic loads experienced during takeoff, hover, and landing phases, while the secure locking prevents loosening even under sustained vibration from high-speed rotor operation. The set of four caps allows complete coverage for standard agricultural drone configurations, with each cap individually tested for thread integrity and locking torque specifications before shipment.

- OEM-compatible specifications guarantee seamless integration with existing EFT drone platforms without modification
- Lightweight design minimizes impact on drone payload capacity while maintaining structural rigidity
Applications and Use Cases
- Agricultural spray drone operations where arm stability is critical for precise pesticide and fertilizer application across crop fields
- Long-duration flight missions requiring secure arm locking to prevent structural fatigue and mission-critical failures
- High-speed maneuver operations in precision agriculture where dynamic loads test arm joint integrity
- Maintenance and reassembly procedures for EFT drone platforms where secure arm fastening ensures safety during ground operations
- Multi-mission configurations where drone arms are frequently attached and detached between different payload systems
How to Use
Before installation, inspect the arm mounting interface and lock cap threads for any debris or damage that could compromise the seal. Align the lock cap with the arm mounting hole, ensuring the threaded portion engages smoothly with the receiving threads. Hand-tighten the cap initially to establish thread engagement, then use the appropriate torque wrench to apply the manufacturer-specified locking torque. This ensures adequate clamping force without over-tightening, which could strip the threads or damage the arm structure. Apply consistent rotational pressure until you feel the positive mechanical lock engage, indicating secure fastening.
After installation, perform a visual inspection to confirm the cap is fully seated and flush with the arm surface. Gently attempt to rotate the cap by hand to verify it does not move, confirming the lock mechanism is functioning correctly. During regular maintenance intervals, inspect the lock caps for signs of loosening, corrosion, or thread degradation. If any cap shows signs of wear or fails the manual rotation test, replace it immediately with a new unit from the set. Store unused caps in a dry environment to preserve the anti-corrosion coating and maintain thread integrity for future use.
Frequently Asked Questions
Are these lock caps compatible with other EFT drone models besides E416P, E616P, and E410P?
These caps are specifically engineered for E416P, E616P, and E410P models with 40mm diameter arm interfaces. While other EFT models may have similar arm designs, we recommend verifying the exact diameter and thread specifications before purchasing. Using incompatible caps could result in loose connections or forced fitment that damages threads. Contact our technical support team with your drone model number for compatibility confirmation.
What is the recommended locking torque specification for proper installation?
The standard locking torque for 40mm EFT arm caps is typically in the range of 12-15 Nm, though this may vary based on your specific drone configuration. Always refer to your EFT drone manual for the exact torque specification. Using a calibrated torque wrench ensures you apply the correct force without over-tightening, which could strip threads or under-tightening, which could allow loosening during flight. Our support team can provide the specific torque value for your model if your manual is unavailable.
How often should I inspect or replace these lock caps during regular maintenance?
Inspect lock caps every 50 flight hours or monthly, whichever comes first, for signs of loosening, corrosion, or thread wear. In agricultural spray operations with chemical exposure, inspect more frequently as corrosive residues can accelerate degradation. Replace caps immediately if you notice any loosening, visible corrosion, or if the cap rotates when hand-tested. The four-piece set allows you to replace individual caps without purchasing a complete new set, though we recommend replacing all four simultaneously for consistent performance and safety.
When will I receive my order?
Orders are dispatched within 1-5 business days from our Bengaluru warehouse. Delivery takes 7-8 days to most locations across India.
What is your return and warranty policy?
We offer a 7-day return policy on manufacturing defects only. Contact support within 7 days of receipt for free replacement or full refund. Not applicable for user damage or misuse.
Are bulk discounts available?
Yes, wholesale pricing for orders of 10 or more units. Contact our sales team via WhatsApp or email for a customized bulk quote.
