Leitech 403815 Leitech Go-No Go Plug gauge 6H Size : M12 x 1.25, Depth : 48mm Hi Res, Reading of 0.1 mm

The Leitech Combi Gauge represents the basic patented idea in The System Leitech - the capability of measuring both thread quality and thread depth in one single operation.
When the Combi Gauge is screwed in to a thread hole, the scale divided telescope sleeve is pushed up in the handle. The thread depth can then be read directly on the sleeve.

Leitech High-Resolution Gauge, which has a measuring accuracy of 0.1 mm

If measurement of depth of the thread hole is not needed – we recommend a Traditional Leitech Gauge.

• Accuracy of the etching on the scale is +/-1um (1micro-meter) (+/-0.000040").
• Repeatability: Repeatable to the width of one line, which is 0.003" / 0.005" (3 to 5 thousandths) / 0.08mm / 0.13mm.
• Accuracy of Depth - Depends on depth calibration of the gauge, and operator proficiency.
