The same high quality washers that are supplied with BHJ Honing Plates are also available separately for use as a head bolt or stud washer.

The durability of these washers has been proven by their daily, repeated use on honing plates by some of the largest production engine rebuilders in the country. The Head Bolt Washers are manufactured from C1050 high carbon steel and heat-treated to 45-50 Rc making them stronger than competitive brands and an excellent choice for use in your engine assembly.

Available in sizes to suit 3/8" (10mm), 7/16" (11mm), 1/2" (12mm) and 9/16" (14mm) head bolts or studs in bulk quantities.
