Thread Depth Gauge with Graduation Scale Ojiyas

The DSG series inspects pitch diameter and effective length of female screw threads from M2 to M18, enabling simultaneous two-point measurement to reduce production time and costs. Two types are available: standard DSG and high-spec DSG-HS for precise readings in deep holes. Replaceable gauge parts, a zero-setting master, and a removal tool are available for maintenance and size changes.
