Small Fixing Screw for Engine Adaptor Assemblies

This O.S. Engine OS22826131 adaptor fixing screw serves as a replacement fastener for securing adaptor assemblies on nitro and glow RC engines. The CSM3X8 code in the designation indicates the screw profile matched to adaptor fittings and flange mounts.

Although a minor component, it helps preserve correct alignment between adaptor and engine output during servicing or rebuilds. It is intended to replace original hardware where a CSM3X8 style fixing screw is specified.

Always confirm that the replacement provides the correct thread engagement and seating depth for your adaptor and crankcase interface before finishing installation. Regular checks during maintenance help avoid loose fixings and maintain reliable adaptor alignment while the model is in use.

How can I check compatibility with my adaptor?

Measure the adaptor hole and thread form to ensure they accept a CSM3X8 screw, and compare seating depth to avoid contact with rotating parts.

Where should I source replacements?

Obtain this part identified as O.S. Engine OS22826131 from hobby suppliers or parts listings that stock model engine fasteners and adaptor hardware.

Are there safety checks to do after fitting?

After installation, verify the screw remains tight following a short run, and recheck after the first heat cycle to ensure no settling or loosening occurs.
