Contact Nuts

Cal Fasteners is one of few distributors to offer these specialized electrical hardware products. These fasteners consist of a single nut with two washers attached: a conical washer manufactured from spring steel with a zinc plating, and a flat washer made from a special, tin-plated copper alloy that provides excellent conductivity.
Our contact nuts are used in a variety of electrical applications, including in test blocks for 100 and 200 amp electrical switchboards and panel boards.
