Outside Micrometers The Outside Micrometer is a precision measuring instrument designed for accurate external dimension measurement of components, shafts, wires, tubes, machined parts, and precision-engineered products. It is one of the most widely used measuring tools in manufacturing, machining, quality control, metrology laboratories, tool rooms, and inspection departments. Manufactured with carbide-tipped measuring faces for long-lasting wear resistance and accuracy, the micrometer features a satin chrome graduated scale for glare-free reading, a positive locking clamp for measurement retention, and a ratchet stop mechanism that ensures consistent measuring force and repeatable results. Available in both Metric and Imperial models, with standard and high-resolution versions, the Outside Micrometer is suitable for a wide range of industrial measurement applications.
