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.
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.
