Hexagon Bolts

Hexagon bolts are partially threaded fasteners unlike hexagon set screws which are fully threaded. The advantage of a bolt is that there are no threads in the hole for tighter tolerances. The hexagon head enables the bolt to be tightened with a spanner or a socket. Hex bolts are used with a variety of nuts and washers and are available in a wide range of diameters and lengths in zinc plated finish.
