Mitutoyo 368-169 Holtest Vernier Inside Micrometer 40-50mm Range

Features:  The Mitutoyo 368 series Holtest vernier inside micrometer has three-point contacts for self-centering measurement of the inside dimension (ID) of bores, and a vernier scale in metric units for taking precise ID measurements. It also has a ratchet-stop mechanism that helps provide uniform pressure for precise, repeatable measurements.The micrometer is made of high-grade tool steel for durability and has a satin chrome rust- and glare-resistant finish. The vernier scale is graduated to 0.001mm or 0.005mm depending on the model. The measuring faces are carbide-tipped or TiN-coated for wear resistance depending on the model. The micrometer comes with a fitted case for storage.Micrometers are precision measuring instruments that use a calibrated screw to measure small distances. These measurements are translated into large rotations of the screw that are then able to be read from a scale or a dial. Micrometers are typically used in manufacturing, machining, and mechani
