About 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 60 degrees 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.

About Spiral Flute Taps

• Are used for machine tapping in all blind hole applications especially in soft metals that produce long stringy swarf such as aluminium copper and magnesium. Manufactured from HSS-Co5 this modern design tap uses the shear action provided by the spiral flutes to draw the swarf out of the hole which minimises swarf clogging when tapping deeper holes.
