20x M4 Hexagon Nuts for RC Helicopter General Parts HI2505003 Hirobo  [HI2505003]

M4 Hexagon Nut Kit Description

This Hirobo HI2505003 kit includes twenty M4 hexagon nuts intended for general RC helicopter parts and small-scale model assemblies. The M4 thread size makes them suitable for a variety of mounting points including frames, linkages and servo or swashplate connections.

They act as basic fastening components during upkeep and tuning, allowing pilots and builders to replace worn or missing nuts during routine checks. Fit with an M4 hex key or socket and ensure proper thread alignment to prevent damage to bolts.

Storing these nuts with common spares reduces repair time at the field. When required, combine correct engagement with a suitable threadlocker to reduce loosening under vibration and help preserve assembly alignment.
