Description

1.1/2″ x 11 BSPT 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 Pipe Taper (RC Series Pipe Taper) is based on the Whitworth thread form – a symmetrical V-thread with an angle of 55º.
BSPT has been widely adopted internationally for interconnecting and sealing pipe ends by mating an external (male) with an internal (female) thread.
The thread diameter increases along the length of the thread allowing the coupled pipes to form a seal when torqued as the flanks of the threads compress against each other.
The taper is “1 to 16”, meaning that for each 16 mm increase in the distance from the end, the diameter increases by 1 mm.
