Speedmaster®
5/16" Chromoly Steel Black Oxide Hardened Ground Washer
Overview
PCE flat washers are machined from tough 4130 chromoly steel, heat-treated to proper hardness, and parallel-ground so that stress loads are more evenly distributed and torque readings are more accurate. They can also be used on main bearing caps, rocker arm stands, and other engine components and can be used over and over again.
