UN Thread Ring Gauge TRGUN001


UNC, UNF or UNEF if the diameter-pitch combination is from the “coarse”, “fine” or “extra fine” series, and may also be followed by a tolerance class. Example :6-32 UNC 2B (major diameter: 0.1380 inch, pitch: 32 tpi) Unified Screw Threads UNC, UNF and UNEF

A wide range of GO / NO-GO fixed gauges are available for checking inside and outside threaded diameters, so as to ensure accuracy during the machining process. This ensures a “snug” fit between threaded components, which in turn phases out the loosening of screw-fastened joints in your final work piece.

What Thread Ring Checks?
  • A Thread Ring GO Gauge Checks The Maximum Minor Diameter And The Maximum Pitch Diameter Size In A Part.
  • A Thread Ring NO-GO gauge checks for the hole not to exceed the minimum pitch diameter size on a part.
Supplied As
  • GO / NO-GO Ring.
