O.S. Engine OS79871430 Hexagon Socket Head Cap Screw M4x30 10pcs  [OS79871430]

Hexagon socket cap screws for RC hardware

This M4x30 hexagon socket head cap screw set from O.S. Engine is a straightforward hardware pack intended for RC-scale use, supplied as 10pcs per pack. The parts are intended to serve general fastening roles on RC engines, mounts and small structural assemblies where M4 thread engagement is required.

Installation notes: use the correct hex driver to avoid rounding the socket, engage sufficient thread length in mating components, and avoid excessive torque that can strip threads or deform thin mounting flanges. A medium-strength thread locker may be used on threaded metal-to-metal joints if vibration resistance is needed, remembering this is for RC-scale applications only.

Tuning and maintenance role: these cap screws act as basic replacement fasteners for engine mounts, motor mounts and accessory brackets, helping maintain alignment and reduce movement under load when properly torqued and checked regularly during setup or race-day maintenance.
