About this gauge

Snap gauges: what they are and how to choose

Snap gauges have a wide contact area and apt contact pressure, which suits fast, repeated checking on a production line. Single-end progressive, double-ended and I-type styles are available.

Snap gauges check external diameters. For internal bores use a plain plug gauge.

Custom dimensions can be made. Share the size and tolerance on the quote page.
