UNF 1/2″ Hex Set Screw (Fully Threaded Bolt) Zinc Plated Grade 8.8 / 5

UNF 1/2″ Hex Ste Screw (Fully Threaded Bolt) Zinc Plated Grade 8.8 / 5 1/2 UNF hex set screw manufactured with a bright zinc plating (BZP) offering a mid-level corrosion resistance. 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. Specification: Grade 8.8 / 5
