Also known as backup washers, these square washers are for use with blind rivets for extra support when fastening into soft material. They fit into slots and channels and have flat sides to keep them from rotating. They are wider and thicker than most round washers, making them good for distributing heavy loads. They are zinc-plated steel for corrosion resistance in wet environments.
