Goliath Hexagonal HSS Die Nut for External Thread

High Speed Steel (HSS) Dienuts

• Goliath solid High Speed Steel (HSS) Dienuts are used for cutting of new 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 accessability.
• HSS Dienuts have a vastly longer tool life than Carbon dies as well as producing more accurate threads.

UNC (Unified National Coarse)

• This thread form was introduced in 1948 as an attempt to standardise thread forms in the USA, Canada and the UK.
• The thread profile of UNC is the same as for metric threads and is described in the JIS B0206 standard.
• The thread is described by its major diameter and the number of threads per inch of length (TPI).
• This thread series is commonly used in the mass production of bolts, screws and nuts.
• It is used for threading into lower tensile strength materials (bronze, brass, aluminium and plastics) to obtain the best resistance to stripping of the internal thread.
• It is also used on quick assembly or disassembly or if corrosion or slight damage is possible.
