Select from the sizes available.

As used in the Belchers Workshop for vehicle restorations.

Unlike hexagon bolts, which are partially threaded, the hex head set screw has a fine thread extending up to the underside of the head. This ensures a secure and tight fixing every time without the worry of running out of thread. 

Also known as a ‘fully threaded bolt’, the hex head also allows for higher torque to be applied with a range of conventional tools making them a versatile choice.
