Form C washers, also known type C washers, and a standardised flat with a slightly larger OD than normal flat washers. Form C washers are popular for both metal and timber applications, as the larger diameter helps to distribute the load evenly. Washers are used in conjunction with a threaded fastener i.e., a bolt and nut, to help prevent the screw from loosening and to distribute the load from the nut or bolt head more evenly and over a larger area. These washers are made to BS 4320 C specifications.
