What is the purpose of a head bolt washer?

A head bolt washer distributes the clamping force of the bolt over a larger area of the cylinder head. This helps prevent the bolt head from digging into the cylinder head material and ensures a more even and reliable seal for the head gasket.

What are the dimensions of this washer?

This S&S Cycle washer has an outside diameter of .515 inches, an inside diameter of 1 inch, and a thickness of .250 inches. These specific measurements are important for proper fitment with compatible head bolts.

Are these washers sold individually or as a set?

The product listing is for a single head bolt washer. For engine builds, you will typically need multiple washers, so be sure to order the correct quantity for your specific application.
