O.S. Engine OS22025807 Mounting Screw M2.6x18 for RC engine mounts  [OS22025807]

M2.6x18 mounting screw overview

This M2.6x18 mounting screw from O.S. Engine is an RC-scale accessory intended to fasten engine-to-mount connections on model engines and mounts. The designation M2.6x18 indicates the nominal thread size and length shown in the product name, and the part functions as a basic mechanical fastener within engine mounting assemblies.

In practice this screw secures engine brackets and mount plates so the engine remains aligned under running conditions. Proper installation—starting threads by hand, tightening evenly across mounting points, and checking for looseness after initial runs—helps maintain alignment and reduces vibration transfer to surrounding components. As a small replacement part, its role in tuning is indirect: a secure mount keeps engine position consistent, which supports repeatable carburetion or ignition adjustments on glow or nitro model engines.

Because this is an RC-scale mounting component, verify thread size and length match your mount holes before use, and replace any damaged fasteners rather than reusing stripped threads.
