Head Bolt Washers

These are not just another head bolt washer. Our washers are made from 4130 chrome-moly steel, heat-treated to the proper hardness, and finish ground on both sides. They are engineered to give the engine builder more reliability and accuracy in reading and holding torque tolerances on heads, main bearings caps, and other engine components. Washers can be used repeatedly without chance of breaking, bending, or galling.
