MechNexa Engineering answers the most common questions buyers and engineers ask about precision gauges, gauge selection, dimensional inspection, and ordering.

What is a plug gauge? A plug gauge is a cylindrical tool used to inspect whether an internal hole or bore is within dimensional tolerance using the Go / No-Go principle.

What is the difference between plug and ring gauges? Plug gauges check internal dimensions (holes), ring gauges check external dimensions (shafts).

What is Go / No-Go gauging? Go gauges check the minimum material condition; No-Go gauges check the maximum. Together they confirm a dimension is within tolerance.

Which industries use thread gauges? Automotive, aerospace, defence, general engineering, and any industry with threaded components.
