Goliath solid High Speed Steel (HSS) Die Nuts are used for cutting of new male threads as well as extending / cleaning / resizing of existing threads where a button die is not suited due to work space restrictions and / or on site thread accessibility.
HSS Die Nuts have a vastly longer tool life than Carbon dies as well as superior thread accuracy.

This thread form was developed by Sir Joseph Whitworth in 1841.
