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

Secure Mounting Screw M3x14

This M3x14 mounting screw serves as an RC engine fastener to secure small model engines onto their mounts. Offered individually, it is intended for applications requiring an M3 threaded fixing on engine mounts or mounting plates common to nitro or small gasoline RC vehicles.

Prior to tightening, confirm the screw clears internal parts and that threads fully engage. Use the appropriate driver to avoid rounding the head and apply measured torque to prevent thread stripping or mount deformation. For improved retention during running, a compatible removable threadlocker can be used, and fasteners should be rechecked after initial running sessions.

Maintenance checks are recommended: inspect for stripped threads or heavy corrosion, replace any damaged screws, and ensure the mounting surfaces are flat and gap free to keep engine alignment consistent for predictable performance.
