As the most common threadform in the USA and Canada, Unified National Coarse (UNC) hex bolts are now mostly found in the UK in imported products, such as vehicles, but can also be found in many other places. UNC fasteners are sized in imperial units, similar to BSW fasteners, but the UNC thread profile has a 60° angle, while BSW fasteners have a 55° angle. We supply UNC hexagon head bolts in a wide range of sizes. We also offer UNC hexagon nuts, threaded bar, hex setscrews and socket cap screws.
