Quality washers for many applications, such as attaching accessories, chassis components, etc. They are not of the hardness required for use on cylinder heads, mains and connecting rods. Available in black oxide and stainless steel. Stainless demonstrates excellent corrosion resistance. Washers have over-sized I.D. (inside diameter) to clear most under-bolt head radii. Available for 1/4, 5/16, 3/8, 7/16, 1/2 and 10mm shank bolts and studs.
