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

M4x30 Hex Socket Screws for RC Use

This M4x30 hexagon socket head cap screw set from O.S. Engine OS79871430 is a basic hardware pack for RC applications, supplied as a 10-piece pack. These screws suit general fastening duties on RC engines, mounts and small structural parts where M4 thread engagement is appropriate.

Installation notes: select the correct hex driver to prevent cam-out, ensure adequate thread engagement in mating parts, and avoid over-tightening which can strip threads or deform thin flanges. For metal-to-metal joints exposed to vibration, a medium-strength thread locker can be applied; this product is intended for RC-scale use.

Maintenance note: these cap screws function as replacement fasteners for engine and motor mounts plus accessory brackets, helping preserve alignment and limit movement when torqued and inspected as part of routine setup or event maintenance.
