Also known as a pin gauge, a plug gauge is used for quick assessment of the bore or diameter of an object. Consisting of specified tolerance of GO and NOGO side.

0.20mm diameter to 19.45mm diameter.Reversible pin gauges have double the length of life compared with non-reversible gauges.
Gauge life and dimensional stability are guaranteed based on well-proven manufacturing processes and a robust quality management system.
The Pin Gauges are manufactured to BS969 – 1982 using the component hole tolerancing as the basis for determining the gauge manufacturing tolerances. In addition, gauges can be supplied to DIN and ANSI standards.
Gauge Pins are a standard length of 50mm and are held in a black hexagonal handle marked with the Go- and No-Go dimensions color-coded green and red for easy identification.

6.00mm diameter to 65.00mm diameter. Taper-Lock gauges are used for conventional hole diameter inspection as well as the gauge base for additional features such as hexagonal holes, holes requiring a recess in the leading face of the gauge, square and rectangular gauges, and large diameter concentricity gauges.
Gauge life and dimensional stability are guaranteed based on well-proven manufacturing processes and a robust quality management system.

Whistle-style steps are ground on the Go gauge member of a pin or plug gauge to give an economic solution for checking the depth of blind holes, stepped holes, and counter-bores. Go and No Go depth steps can be ground on the same gauge member.

Plug gauge and snap gauge are essential measurement tools. There are some differences between the two gauges. See the comparison table below to get a realistic concept.
Plug Gauge |
Snap Gauge |
1. Plug gauges are used to check the holes |
1. Snap gauges are used to check gauge shaft |
2. Assess whether the hole dimension within the specified tolerance |
2. Access to the both cylindrical and non-cylindrical parts |
3. GO gauges determine the lower limit of hole |
3. GO gauges are the size that corresponds to a higher limit of shaft |
4. NO-GO gauges determine the upper limit of the hole |
4. NO-GO gauges are the size that corresponds to lower of the staff |
