Silencer mounting screw overview

This O.S. Engine OS44925300 silencer assemble screw is an RC-scale mounting fastener marked M4X110 and intended for use with silencers listed as F-5040 and FSa-110. It serves as the mechanical link between the cylinder head outlet and the muffler body, keeping exhaust components aligned during the vibration typical of nitro RC models.

On fitment, ensure the screw threads engage cleanly with the silencer insert and avoid cross-threading by starting the thread by hand. Keep the assembly straight before final tightening and check for correct seating; secure with appropriate torque but do not over-tighten. After installation, inspect for leaks or looseness following an initial run.

Properly fitted, this fastener preserves exhaust alignment which can influence backpressure and engine consistency on nitro setups. Straight, secure mounting reduces stress on the silencer and nearby parts such as the manifold and mounting studs.

How does this screw secure the silencer to the exhaust?

The screw passes into the silencer insert and threads into the outlet or mating insert, clamping the muffler body against the cylinder head outlet to maintain alignment under vibration.

What exactly does M4X110 indicate?

M4 denotes the metric thread diameter and pitch standard, while 110 refers to the length of the threaded portion as stamped on the part. Verify these match the silencer insert before fitting.

Any tips to prevent vibration loosening?

Start the screw by hand to avoid cross-threading, tighten to firm seating without over-torquing, and consider a medium-strength threadlocker if vibration causes repeat loosening. Re-check after a short run.
