Hirobo HI2505008 M3 Claw Nut Pack 5pcs  [HI2505008]

Compact M3 claw nuts for small helicopter hardware

This pack contains five M3 claw nuts made for RC-scale helicopter hardware and other small model assemblies. They suit M3 threaded connections commonly used on rotor linkages, small mounts, and tight frame attachment points where a low-profile nut is required.

To install, thread the nut onto the matching M3 stud or bolt and tighten until the claw bites the mating surface. Check that the nut holds without play and re-check fastenings during initial bench tests and after flight sessions. Use the correct wrench or driver to apply controlled torque and avoid over-tightening which can damage threads.

Function in setup and maintenance: these clutch-style nuts act as locking fasteners for minor components, helping to keep alignment and prevent loosening from vibration during normal RC helicopter use. When replacing lost or worn nuts, confirm the M3 thread and ensure sufficient clearance in compact assemblies.
