Outer diameter micrometer for precise external dimension measurement. It uses a helix screw principle to determine the distance between the two measuring faces. This tool is designed for measuring a variety of external dimensions with high accuracy. Key benefits - High resolution: division value of 0.01 mm for precise tolerance control. - Wide range: maximum measurement range not more than 300 mm, available in 25 mm segment sizes (0-25 mm, 25-50 mm, 50-75 mm, etc.). - Simple, repeatable readings suitable for workshop and quality control environments. Applications - Measuring external diameters of shafts, pins, bushings, and collars. - Quick verification of outer dimensions after turning, grinding, or finishing. - Checking tolerances for assemblies and mating components. Specifications - Measurement principle: external diameter micrometer using a helix screw mechanism. - Division value: 0.01 mm. - Maximum range: not more than 300 mm. - Range segments: 0-25 mm, 25-50 mm, 50-75 mm, and so on up to 300 mm.
