The integrated ratchet stop applies a uniform measuring force to every workpiece, ensuring consistent and repeatable results. Carbide-tipped measuring faces resist daily workshop wear to maintain precise contact over time. Fully mechanical and battery-free, this micrometer delivers dependable accuracy whenever you need to inspect workpieces on lathes, milling machines, or during quality control.
