This mechanical outside micrometer set includes four micrometers, providing a 0-4 in measurement range with 0.0001 in graduations. It features a heat-insulator on the frame to minimize temperature-related expansion or contraction. The spindle and anvil have flat, carbide-tipped measuring faces for wear resistance, and a spindle lock ensures secure measurement locking. A combination ratchet and speeder allows for consistent pressure and faster adjustments.
