Description
Insize 25–50mm Screw Thread Micrometer
The Insize 25–50mm Screw Thread Micrometer is a precision measuring instrument designed for accurate measurement of screw thread pitch diameters within the 25–50mm range. It is ideal for use in machining, inspection, and quality control applications where consistent and repeatable thread measurement is essential.
Featuring a non-rotating spindle, this micrometer ensures stable contact with thread flanks while reducing wear and rotational error. The ratchet stop provides uniform measuring pressure, minimising operator influence and improving measurement repeatability during critical thread inspection tasks.
