Description
Insize 125–150mm Screw Thread Micrometer
The Insize 125–150mm Screw Thread Micrometer is a precision measuring instrument designed for accurate measurement of screw thread pitch diameters across larger metric sizes. It is ideal for machining, inspection, and quality control applications where reliable and repeatable thread measurements are required.
Featuring a non-rotating spindle, this micrometer provides stable contact with thread flanks while minimising rotational error and surface wear. The ratchet stop ensures consistent measuring pressure, reducing operator influence and improving repeatability during critical thread measurement tasks.
