Hirobo HI2505008 M3 Claw Nut Pack 5pcs  [HI2505008]

M3 Claw Nut for RC Helicopters

This pack contains five M3 claw nuts intended for RC-scale helicopter hardware and similar small model assemblies. The part is sized for M3 threaded connections commonly found on rotor linkages, small mounts, and frame attachment points where a compact nut is needed.

Installation is straightforward: fit the nut onto the corresponding M3 threaded stud or bolt and tighten until the claw engagement seats against the mating surface. Verify fit by checking that the nut holds without play; re-check during initial bench testing and after any flight sessions to confirm secure fastening. Use the appropriate driver or wrench for a controlled torque and avoid over-tightening to prevent thread damage.

Role in setup and tuning: these nuts serve as locking fasteners for small components, helping maintain alignment and preventing loosening during vibration and normal RC helicopter operation. When replacing worn or lost nuts, match the M3 thread size and confirm clearance in tight assemblies.
