Notes :
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 tread 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 obtains the best resistance to stripping of the internal thread. It is also used on quick assembly or if corrosion or slight damage is possible.
Spiral Point
Spiral Point Taps are used for machine tapping blind and through holes where there is sufficient clearance to accommodate chips. Manufactured from super tough HSSE-V this modern design tap uses straight flutes supplemented by angular cutting faces at the point to produce a fine finish on the threads. Shallower flutes achieves a stronger cross section allowing the tap to withstand greater cutting forces.
