An Explanation of Unified
Thread Nomenclature |
|
The Unified system of
threads originates and is primarily
used in the USA and comprises of two main groups.
The coarse pitch range is termed as UNC
The finer pitched range is termed UNF (as listed on this page)
The nomenclature of all
Unified threads takes the form of one or two digits,
or a fraction
size, followed by a hyphen, followed by 2 more digits.
Sizes below 1/4" nominal diameter are identified by a series of
gauge numbers
and takes the form of a one or two digit number before
the hyphen.
Sizes of 1/4" or higher simply have the size in inches before the
hypen.
The digits following the hyphen indicate the number of threads per
inch ('TPI')
So as an example, a 4 UNF
thread is fully expressed as a 4-48 thread
This has a diameter of No 4 gauge with 48 threads per inch.
You can find much much
more details of UNC and other threads on our
Thread Data
page including nominal diameters of the gauge sizes
converted to millimeters. |
