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.\u003c\/p\u003e\n\n\u003cp\u003eAfter 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.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eAre these lock caps compatible with other EFT drone models besides E416P, E616P, and E410P?\u003c\/summary\u003e\n\u003cp\u003eThese 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.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the recommended locking torque specification for proper installation?\u003c\/summary\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eHow often should I inspect or replace these lock caps during regular maintenance?\u003c\/summary\u003e\n\u003cp\u003eInspect 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.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eWhen will I receive my order?\u003c\/summary\u003e\n\u003cp\u003eOrders are dispatched within 1-5 business days from our Bengaluru warehouse.
