Bordo UNC Tap Set HSS Hand and Machine Tap - 3032

HSS UNC Hand and Machine Tap Set.
Unified National Coarse 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.
Bottoming Taps have a lead of two threads and are used to ensure minimum thread run-out when tapping to the bottom of a blind hole.
Intermediate Taps have a lead of four threads and are used in most general purpose applications to cut a thread true to a pre-drilled pilot hole.
Taper Taps have a lead of eight threads and are used as a starting tap in difficult or high precision holes.
Manufactured from HSS this general purpose tap is designed for use in medium tensile materials and is for hand or general machine use.
