Precision-engineered stepped washers provide a secure, even clamping surface when installing head bolts or studs on aluminum cylinder heads. The stepped design centers the washer in the bolt hole, preventing movement during torqueing and protecting the softer aluminum from galling or distortion. Machined from high-strength hardened steel and finished for corrosion resistance, these washers ensure consistent torque readings, improved load distribution, and long-lasting performance in high-compression and high-RPM applications. Ideal for performance builds where reliability and precision matter most.
