Steel Shoulder Screws for Binding Barrels

A shoulder adds strength to handle side or shear loads. Pair these screws with a barrel you already have or couple with a different barrel to create a custom fastener. A zinc plating provides corrosion resistance in wet environments. Screw length is measured from under the head.
