Socket Head Cap Screws

 Bolt King is a UK Manufacturer of Socket Head Cap Screws. We typically supply Socket Cap Screws into the Oil & Gas, Petrochemical and Automotive industries. We can offered hot forged Socket Cap Screws from M6 - M52, and CNC bar-turned products from M4 - M200. Smaller socket headed fasteners can be hot-forged with the socket in, which saves valuable manufacturing time, and allows for a cost-saving to be passed on to our customers.

We manufacture to International Standards, as well as customer's drawings. As well as standard Alloy and Stainless steels, we love working with the exotics, including Inconel, Super Duplex, Titanium and many more.
