O.S. Engine OS24025801 Mounting Screw M3x14 Engine Mount Fastener  [OS24025801]

Engine Mounting Screw M3x14

This M3x14 mounting screw is an RC-scale engine fastener intended for securing small model engines to their mounts. The part is sold as an individual mounting fastener and is suitable where an M3 threaded fixing is required in engine mounts or mounting plates used on nitro or small gasoline RC models.

When installing, confirm thread engagement and that the screw length clears internal components before tightening. Use the correct driver for the screw head to avoid rounding, and apply moderate torque—avoid over-tightening which can strip mount threads or deform the mount. For added security during running or tuning, consider using a removable threadlocker compatible with model hardware and recheck fasteners after initial runs.

Routine checks are part of good maintenance: inspect for thread wear or damage, replace any screw that shows stripping or significant corrosion, and ensure the mounting interfaces sit flat without gaps to keep engine alignment stable for predictable performance.
