Go/no-go gauge

For example, there would be two female sections on a gauge to test a threaded male workpiece such as a screw.

This may be initially expressed on the parts drawing in a number of styles; three possibilities may be The associated image is a set of pin gauges used to measure holes only a few millimeters in diameter.

The first go/no-go snap gage for checking thread rolls was invented in 1943 to speed production of parts during WWII.

[6] Once the concept is understood, the principle of operation can lead to all manner of designs where internal grooves, keyways, splines, etc.

If the bolt also closes fully on the field gauge, such a gun is considered unsafe due to high risk of shell case rupture if the cartridge's length happens to be on the shorter end of the spec.

A special match-grade go gauge can also be employed to verify a particularly tight, or shorter-than-SAAMI specification chamber length.

This minimizes case stretch or end-play in order to best control the positioning of an unfired round prior to its firing in a match-grade chamber.

Thus, a standard go gauge may not actually chamber as easily due to these reduced dimensions, even if they are cut properly.
