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.
