O.S. Engine OS79871555 Hexagon Socket Head Cap Screw M5x55 - 10 pcs  [OS79871555]

M5x55 hexagon socket cap screw specification

This O.S. Engine OS79871555 listing covers a 10-piece set of M5x55 hexagon socket head cap screws intended for RC-scale assemblies. The hex socket head accepts a matching hex driver and allows controlled tightening in confined engine and chassis mountings.

Installation notes: use a correctly sized hex driver to fully seat the tool, apply steady moderate torque and avoid over-tightening to protect threads and mounting surfaces. For repeatable assembly and maintenance, confirm thread engagement and consider a removable threadlocker on vibration-prone joints.

Tuning and role: these screws secure engine mounts, motor and gearbox brackets and other structural connections on RC models; keeping fastener lengths and head types consistent helps preserve chassis geometry and serviceability during setup and use.
