O.S. Engine OS22826131 Adaptor Fixing Screw CSM3X8 Replacement  [OS22826131]

Replacement Fixing Screw For RC Engine Adaptors

The O.S. Engine OS22826131 adaptor fixing screw provides a compact replacement fastener designed for securing adaptor assemblies on nitro and glow RC engines. The CSM3X8 label denotes the specific screw form that mates with adaptor fittings and flange mounts.

Although small, the screw plays an important role when servicing or rebuilding adaptor interfaces by helping keep the adaptor aligned with the engine output. It is intended for use where the original adaptor hardware requires a CSM3X8 style fixing screw.

When fitting a replacement, make sure the screw matches the required thread engagement and seating depth for your adaptor and crankcase interface. Regularly inspect these fasteners during engine maintenance to avoid loosening and retain stable adaptor alignment in operation.
