Fixing screw details

This is an RC-scale pump unit fixing screw produced under the O.S. Engine part number OS29067120, identified by the CSM3X18 designation. It is designed to fasten pump assemblies on O.S. Engine pump units and compatible pump hardware, serving as a replacement or spare for maintenance tasks.

When fitting the screw, protect thread form and alignment: begin the screw square to the mating hole, seat components fully, and tighten incrementally to prevent cross-threading. Do not overtighten, as this can damage pump housings or strip threads; check the fastener periodically for signs of thread wear.

For maintenance and reliability, using the correct fixing screw helps preserve pump alignment and the integrity of seals so pump function remains consistent. Having a spare screw available reduces the chance of extended downtime during servicing.

How often should I inspect this screw?

Inspect the fixing screw whenever the pump is serviced or if you notice leaks or misalignment. Regular checks ensure threads remain sharp and the head seats correctly, preventing failures during running.

Are there torque guidelines for installation?

There are no published torque numbers for this part; tighten gently and progressively until components are flush and secure. The goal is to avoid stripping the housing threads while achieving a snug fit.

Will the screw resist corrosion in humid environments?

Corrosion resistance depends on the screw material and finish. Check the part you receive and replace any fastener that shows corrosion to maintain reliable pump mounting.
