A die is used to cut a male thread onto a piece of bar, such as you would find on a bolt.
Dies need to be strong and resilient, so we choose dies that are made from high speed steel, which is superior to the high carbon steel that some dies are made from.
They come with a either a split round head, for use with a diestock, or a full hexagon head.
BSW (British Standard Whitworth) is an imperial coarse thread first used in standard production by Joseph Whitworth during the industrial revolution. Whilst it is still used in engineering applications all across the world it is less common in the UK where metric threads have generally taken over.
