Hirobo HI2505008 M3 Claw Nut Set, 5 Pieces  [HI2505008]

M3 claw nut details for rotor and frame fittings

Five M3 claw nuts are provided in this pack for RC helicopter maintenance and small-model fastenings. They are sized to engage standard M3 bolts and studs often used on swash linkages, mounts, and compact attachment points.

To fit, screw the nut onto the matching M3 stud until the claw section seats against the mating surface. Confirm a snug, play-free fit and re-inspect fastenings during initial test runs and after any flight activity. Use a correct-sized driver to control torque and avoid over-tightening which can damage threads.

Tuning and reliability role: these nuts function as locking fasteners that help preserve component alignment and reduce loosening risk from vibration. When you replace lost or degraded nuts, match the M3 sizing and check for adequate clearance in confined assemblies.
