Engine Mount Fastener M3x14 - O.S. Engine OS24025801  [OS24025801]

M3x14 Mounting Screw Summary

The M3x14 mounting screw is an RC-scale engine fastener intended to secure small model engines to mounting plates. Supplied as a single fastener, it is appropriate where M3 threaded fixings are used in engine mounts common to nitro or small gasoline RC models.

When fitting, verify that the screw length clears internal elements and that there is full thread engagement. Use the correct screwdriver size to avoid damaging the screw head and apply moderate torque to prevent stripping mount threads or deforming the mount. For enhanced vibration resistance, a removable threadlocker compatible with model hardware may be used, and all mounting screws should be rechecked after initial engine runs.

Perform routine inspections: check for stripped threads or corrosion, replace any screw showing significant wear, and ensure the mounting surfaces are in direct contact without gaps to preserve engine alignment and consistent running behavior.
