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

Muffler mount hardware for RC engines

This is a dedicated RC-scale muffler mounting screw intended to secure mufflers and exhaust attachments on model engine setups. It is presented as a single fastening component used where a muffler or exhaust bracket needs a secure threaded connection on nitro or small-scale gas model engines.

Installation is straightforward: align the muffler flange with the exhaust outlet or bracket, insert the screw through the mount point, and tighten until snug. Avoid over-torquing to prevent thread damage in the engine’s mounting boss or muffler flange. Use basic hand tools and check fitment before each run.

In tuning and maintenance routines this screw functions as a basic retention point for exhaust position and orientation. During testing and adjustments, ensure the screw remains secure against vibration and thermal cycling, and inspect it when changing mufflers or during routine engine service to confirm no loosening or wear.
