Socket Countersunk Barrel Nuts In Stock
Socket countersunk head barrel nuts have a standard socket drive. Available with either through hole or blind hole (see stock size chart for availability). The countersunk socket barrel nut has a smooth barrel under the head keeping a smooth sleek look throughout. Socket countersunk sex bolts are ideal in applications where a high strength, flush fixing is required, whereby the countersunk head sits flush into the pre counter-bore holes providing a sleek and continuous flow with the surface of the application.
Within the industry, they are also often referred to as sleeve nuts.
