Description

Washers evenly distribute the load of a threaded fastener and without them you won't get the correct head bolt tension. Pioneer head bolt washers offer an exact fit without compromise. These quality made washers feature hardened steel construction and a black oxide finish. Choose quality and value to complement your head bolts with Pioneer washers.
