UNC | UNIFIED NATIONAL COARSE TAPER

About this item:
  • 1/4" x 20 UNC Taper Chrome Tap
  • Chrome Alloy UNC Taper Hand Tap.
  • Used as thread chasers to clean an existing thread.
  • They can also be used to create a new female thread in non-ferrous metals and plastics.
  • Chrome alloy taps are not suitable for creating precision, safety or critical threads.
  • 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.
