Chrome Button Die, UNC 1" by Bordo

About this item:

• Unified National Coarse (UNC).
• Split circular chrome alloy button dies are most commonly used in conjunction with a die stock handle.
• They can be used as thread chasers to clean an existing thread.
• They can also be used to create a new male thread on non-ferrous metals and plastics.
• Chrome alloy dies are not suitable for creating precision, safety or critical threads.
• The UNC 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.
