A cylinder head screw to suit the UMS 5-125cc — the five-cylinder 125cc four-stroke radial from UMS.
On this engine the component is the cylinder head screws that clamp the head to the barrel.
Why this part matters: these are high-torque fasteners and are commonly replaced when they show stretched threads or corrosion, or simply on a full overhaul. Supplied as a pack of 5, which is how these small parts are normally bought — you rarely need just one.
Fitting note: Torque in a diagonal sequence and in stages, and follow the factory figure.
