Hexagon socket head cap screw for RC use

This M5x15 hexagon socket head cap screw is an RC-scale fastening part intended for secure connections on model engines, mounts and nearby accessories. The head profile fits standard hex drivers and is sized for M5 threaded holes commonly found on engine mounts and accessory brackets.

Use this pack when replacing worn fasteners or when assembling engine mounts, accessory brackets, or small structural joints where a compact head and internal hex drive help avoid protrusions and allow tighter clearances. The parts are suitable for routine maintenance, pre-run checks and basic tuning adjustments.
