Johnson Gage designs and manufactures screw thread inspection systems. Typically, a Johnson Gage refers to an indicating thread gage that inspects features related to a screw thread. Inspection systems can be provided for External or Internal thread, most all thread forms and most thread characteristics. Gages for Screw Thread Inserts (STI) 2020-11-02 Nov 01, 2020 · Screw thread inserts (STI) require the threaded hole to be inspected prior to inserting the threaded insert or coil. The dimensions and tolerances for the gages used to inspect these threads have been a bit confusing over the past 30 years. This confusion has affected metrology labs, gage manufacturers, and gage end users.
The gauge becomes more difficult to use if you are trying to check thread gauge in place and must bend and twist your body, and look in dark places. For those uses and if a standard, common thread gauge is likely, twisting on a test nut or trying out a test bolt will give a tactile confirmation once you have found the right gauge. Inspecting Threads With Thread Gages Is NOT EnoughIn addition to inspecting screw and bolt threads with GO and NOGO ring gages or Tri-roll thread gages, they should also inspect the major diameters of screw and bolt threads using a micrometer, caliper, or a NOGO cylindrical ring gage made at the applicable limits of the major diameter.

The setting plug should previously have been inspected and known to be in good condition, of the correct pitch diameter size and within thread element specifications. The following methods are used to adjust the ring and to insure the proper pitch diameter setting.
