measurement instrument

Quick Summary

A fixed-type gauge is a measurement instrument used in manufacturing and engineering to determine if an object's dimension is within a specified tolerance range. These gauges don't always measure the exact size but rather indicate if the object is within acceptable limits.1

Common examples include:
* Plug gauges: Cylindrical bars used to check the accuracy of holes. A "go" end enters if the hole is correct, while a "not go" end does not.1
* Ring gauges: Used for cylindrical parts, also featuring "go" and "not go" sections.1
* Snap gauges: C-shaped tools with "go" and "not go" jaws for checking diameters, lengths, and thicknesses.1
* Form gauges: Used to check profiles, such as radius gauges for corners and screw-thread pitch gauges for threads.1

Gauge blocks, or Johannsson blocks, are precise steel blocks that can be combined to measure various linear dimensions.1
