About this item:
- 1" x 8 Left Hand UNC Taper HSS Tap
- HSS UNC LEFT HAND Taper Hand and Machine Tap.
- 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.
- 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.
