Leitech Thread Depth Gauge – Combi Gauge
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. The Leitech Combi Thread Gauge is used in the same way as any normal double-ended thread gauge. As the GO side is inserted into the thread hole, the telescoping measuring sleeve retreats into the aluminum body, providing the user with an accurate depth reading of 0.5mm or .025″ resolution per division. The NOT GO side is used in a conventional manner.
