Features & Benefits

The Mitutoyo screw thread micrometer features a hardened steel 60 degree anvil and conical spindle to easily and precisely measure pitch diameters of metric or unified screw threads. A ratchet-stop mechanism provides uniform pressure on a workpiece for precise, repeatable measurements.

  • Measuring surfaces are constructed of carbide to reduce wear
  • Ratchet mechanism provides an audible click to ensure measurement is performed at a constant force
  • Satin chrome finish on the sleeve and laser etched scale on thimble for easier reading
  • Frame has a baked enamel finish for durability and longer lifespan
  • Includes a standard bar for zero-point adjust except for 0-25mm model
  • Supplied in fitted plastic case
