The serrated washer is intended for one-time use, as it’s soft composition disintegrates when removed from the oil pump mounting stud. It secures the conical nut under a light torque specification.

The washer fits into the concave mounting hole on the brass body of the oil pump body. The conical nut is locked into place when the washer deforms. The washer is not reusable once deformed. Sold individually and multiple quantity discounts.
