Mitutoyo 368-262 Mechanical Inside Micrometer 0.35-0.425 in

Product Description

The MITUTOYO 368-262 is a mechanical inside micrometer designed for precise internal bore measurements in the range of 0.350 to 0.425 inches. It uses three hardened-steel anvils spaced evenly at 120 degrees to ensure true axis alignment within the bore, delivering accurate and repeatable readings. The ratchet stop thimble provides consistent measuring force, and the ring-style lock nut holds the setting once the correct reading is established. Graduation is 0.0001 inches, with an accuracy of 0.0001 inches. The satin chrome finish resists corrosion and reduces glare during use. This tool is suited for machinists, toolmakers, and maintenance technicians requiring reliable inside diameter measurement.

The 368-262 is intended for small-bore internal measurement applications in manufacturing, machine shops, and maintenance environments. It is well suited for checking cylinder bores, bushing IDs, and other precision internal features where a standard inside micrometer or bore gauge is the appropriate tool. The solid rod design keeps the instrument rigid during measurement, which is critical when working in tight-bore applications near the lower end of the 0.350 to 0.425 inch range.

Installation Notes

This instrument is used by machinists and metrology technicians and does not require mechanical installation. Handle the anvil contact surfaces with care to avoid damage that could affect accuracy. Store in the provided case when not in use. The unit is not factory calibrated; verify against a known standard before use in critical measurement applications.
