5/16 UNF hex set screw 

5/16 UNF hex set screw manufactured with a bright zinc plating (BZP) offering a mid-level corrosion resistance.

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. 

Versatile and when coupled with the 5/16″ UNF nuts sees these hex head set screws widely used across many industries by DIY enthusiasts and professionals alike.
