FAQ

What is the difference between USS and SAE flat washers?
USS flat washers have a larger inside and outside diameter and are usually thicker. SAE flat washers fit closer to the bolt and have a smaller outside diameter, so they suit tighter spaces and machinery.

Which washer goes first, the flat washer or the lock washer?
The flat washer goes against the part and the lock washer sits between the flat washer and the nut or bolt head.
