O.S. Engine OS22025619 Exhaust Mounting Screw 702P  [OS22025619]

Compatibility and fit notes

This O.S. Engine OS22025619 component is offered as a single screw to secure mufflers and exhaust attachments on small-scale gas and nitro model engines. It is intended for use where a threaded connection between a muffler flange and the engine or bracket is required.

Fitting is straightforward: align the muffler flange with the exhaust outlet or mounting bracket, insert the screw through the flange, and tighten until secure. Avoid excessive torque to protect the engine boss threads and the muffler flange. Use appropriate hand tools and confirm engagement prior to running the engine.

When selecting or replacing the screw, confirm thread and flange compatibility with your muffler and engine mounting points. Regular inspection after usage and whenever changing exhaust parts will help maintain a secure, reliable fit.
