Cotter Pin Wire Pic1
Among the many different parts used in engine valve assemblies, retainer locks are used to fasten valves, springs and retainers.
Retainer locks have a slightly tapered shape used to wedge the retainer into place, and a slight bulge in the center that holds the valve in place. This complex shape is enabled by Tokusen’s shaping technology.
