Description

1.1/2″ x 8 BSF HSS Die Nut – Goliath
Hexagonal HSS Die Nut for External Threads
High Speed Steel (HSS) Die Nuts
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.
British Standard Fine thread form was based upon the British Standard Whitworth (BSW) but has a finer thread (more threads per inch for a given diameter).
The thread form was first introduced in 1908 and is specified in BS84:1956.
When used on external threads this series has greater tensile stress area than coarse threads of the same size.
Fine series threads will resist stripping out better than coarse threads in areas where the external and mating internal threads are subjected to loads equal to or greater than the capacity of the screw or bolt.
Fine threads are also used where the length of engagement is limited or where wall thickness demands a fine pitch.
