Bordo 1/4" x 20 UNC Chrome Alloy Die Nut 4842-1/4

1/4 x 20 UNC Chrome Alloy 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.
