The Camloc 1/4 Turn (2600 Series) fasteners are very easy to use making detaching and attaching panels very easy. Each of these pieces are designed to work together so your panels fit perfectly together.The receptacle is mounted to the frame that the removable panel will be attached to, it can either be riveted or screwed into place. The threaded version of the receptacle is held in place by the hex nut. The Camloc fastener then mounts through the panel and frame and into the receptacle where it locks into position. The retaining washers are designed to retain the Camloc 1/4 turn fasteners and hold them tight against the outer panel, and are recommended to be used for all fasteners with a grip length more than 3.80mm.
