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

Hexagon socket head cap screw M5x55

This O.S. Engine OS79871555 listing describes a set of hexagon socket head cap screws sized M5x55 supplied as a 10 pcs pack for RC-scale use. The item is intended as a fastener for model assemblies where an M5x55 length is required; its hexagon socket head form is suitable for use with a matching hex driver and allows controlled tightening in confined RC mountings.

Installation notes: use a properly sized hex driver to engage the socket fully, apply steady, moderate torque and avoid over-tightening to protect threaded components and mounting surfaces. For repeatable results in tuning or maintenance, check thread engagement and consider threadlocker when securing parts that experience vibration.

Tuning and role: these screws are used to fix engine mounts, motor and gearbox brackets, and other structural connections on RC models; choosing consistent fastener length and head type helps maintain chassis geometry and serviceability during setup and track use.
