Use these washers to evenly distribute the load under bolt or screw heads and nuts when fastening. They can also act as spacers.
A286 stainless steel washers withstand high temperatures. They have good chemical resistance and may be mildly magnetic.
USS washers generally have a larger ID and OD than SAE washers.
