Mitutoyo 125-111 Screw Thread Micrometer, 50 to 75 mm, 0.6 to 0.9 mm/44-28TPI

Description

The Mitutoyo 125-111 Screw Thread Micrometer is an analog micrometer designed to directly measure the pitch diameter of 60° metric and Unified screw threads. It has a measuring range of 50 to 75 millimeters and is specifically calibrated for metric threads with a pitch from 0.6 to 0.9 mm and Unified threads from 44 to 28 threads per inch (TPI).

Key features

• Specialized anvils: The micrometer features a fixed 60° V-anvil and a conical spindle that fit into the helical groove of a screw thread to measure its pitch diameter. This configuration provides a more direct measurement than standard micrometers and eliminates the need for calculations.
• Constant force mechanism: A ratchet-stop mechanism applies a uniform pressure to the workpiece, which helps ensure consistent and repeatable measurements.
• Measurement scale: The spindle and sleeve have a satin chrome finish with laser-etched graduations for easy reading.
• Durable construction: The measuring surfaces are constructed from carbide to resist wear and maintain accuracy. The frame has a durable baked enamel finish.
• Case and standard bar: The micrometer comes with a fitted plastic case and includes a standard bar for setting the zero point.
