There are three standard thread series in the Unified screw thread system that are highly important for fasteners UNC coarse UNF fine and 8 UN 8 thread 1 UNR Threads The UNR thread is a modified version of a standard UN thread The single difference is a mandatory root radius with limits of 0 108 to 0 144 times the thread pitch
Types Thread depth gages measure the depth of the thread surface in a hole Flush pin depth gages are go no go functional gages that rapidly assess the depth of the opening Depth rules allow quick assessment Typically depth rules are used in applications where precision is not a high priority Combination depth angle gages indicate the depth and orientation of a hole
In fact it is not possible to gage a locking type insert because of the locking coil KATO offers two types of STI Thread Plug Gages for unified sizes Working Gages Recommended for production use since their greater tolerance allows for more wear Reference Gages Pitch diameters at or very close to the basic size and are to be used as master gages KATO
Thread gauges traditionally consist of multiple blades that can be used to measure the pitch The blades sit within a tool that resembles a pen knife The blades can then be twisted out of the tool when in use How to use a thread gauge To use a thread gauge first match the type of thread to the gauge For example attempting to measure

A thread gauge also known as a screw gauge or pitch gauge is used to measure the pitch or lead of a screw thread Thread pitch gauges are used as a reference tool in determining the pitch of a thread that is on a screw or in a tapped hole This tool is not used as a precision measuring instrument rather it allows the user to determine the profile of the given thread and
The Snap Gauge is the gauge which is U shaped Go and Not Go type gauge It has jaws by which it checks the accuracy and tolerance In order to measure the parts it has to pass a Measurement and another one has not to pass the Measurement That is called Go and Not Go measurement Here Go is a high or maximum limit and the Not Go is the low or minimum limit
