UNCUNIFIED 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. Spiral Point Taps are used for machine tapping blind and through holes where there is sufficient clearance to accomodate chips. Manufactured from HSS-Co5 - 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 achieve a stronger cross section allowing the tap to withstand greater cutting forces.
