Hirobo M4 Hexagon Nut Pack Overview

This Hirobo HI2505003 M4 hexagon nut pack contains 20 pieces designed for RC-scale helicopter general parts and small model assemblies. The listing describes M4 threaded hex nuts that suit M4 fastening needs on frames, linkages, swashplate mounts and similar connection points.

The component serves as a basic fastening item for maintenance and tuning tasks, letting hobbyists swap out lost or worn nuts during standard service. Installation is straightforward: use an M4 hex driver or matching socket to tighten, and verify correct thread engagement to prevent cross-threading.
