Description
About this item:
- 1-1/8″ x 7 UNC Chrome Die Nut
- Unified National Coarse (UNC).
- Die nuts are commonly used when a button die is not suited due to work space restrictions and / or on site thread accessibility.
- 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.
