INSPECTION TOOL NUT AND INSPECION GAUGE 5 IN 1

This gauge can be used to inspect: M22 x 1.5 wheel studs, 33MM wheel nuts, and hub-piloted wheel bolt holes. This gauge is precision machined to tight tolerances that are not affected by the day-to-day work environment and coated to prevent rust.

Inspecting studs for Under Diameter
The 5-in-1 gauge inspects the stud for under diameter by inserting the gauge over the threaded end of the stud. If the stud enters the gauge more the first 4-5 threads, replace it and contact the stud manufacturer for specifications.
Inspecting 33MM Nuts
We begin by checking the top of the nut at the threads, insert the gauge by first removing the key chain, turning it upside down, the scribe line on the outside of the gauge should not enter the threaded area of the nut. Remove any nut from service where the gauge enters past the scribe line at the threads and contact the manufacturer for dimensional specifications. Next, with the key chain already removed, insert the gauge into the bottom of the nut. Again, the scribe line should not enter the threaded area of the nut. Remove any nut from service where the scribe line enters past the threads (not flange washer) and contact the manufacturer for dimensional specifications.
Inspecting Hub-Pilot Bolt Holes
The 5-in-1 gauge checks the bolt hole for elongation/foreign material and for SAE size recommendations (26MM –0.0mm +1.0MM).  The Gauge will not pass through the bolt hole if it meets SAE sizing. It is possible to have a larger bolt hole, if there is no elongation or distortion contact the manufacturer for specifications before returning the wheel to service.
