It reads in decimal inches with a graduation of 0.001 inches and an accuracy of 0.0001 inches, making it suitable for demanding dimensional inspection work in machine shops, maintenance facilities, and manufacturing environments. The friction thimble provides consistent measuring pressure to reduce operator-induced error. Measuring faces are solid carbide for wear resistance and long service life. A standard for micrometer head calibration is included, and the unit ships pre-calibrated.\u003c\/p\u003e\n\u003cp\u003eThis micrometer is used for measuring the internal diameter of bores, cylinders, housings, and similar features where high accuracy is required. It is well suited for inspection of engine cylinders, pump bores, valve bodies, and precision machined components. The 2 to 12 inch range, combined with five included extension rods, allows a single instrument to cover a wide span of bore sizes without switching tools. It is used by machinists, metrology technicians, and maintenance professionals in industrial, manufacturing, and heavy equipment service settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasuring range of 2 to 12 inches with 0.001 inch graduation\u003c\/li\u003e\n  \u003cli\u003eAccuracy of 0.0001 inches for high-precision bore measurement\u003c\/li\u003e\n  \u003cli\u003eFriction thimble ensures consistent, repeatable measuring pressure\u003c\/li\u003e\n  \u003cli\u003eSolid carbide measuring faces resist wear for extended service life\u003c\/li\u003e\n  \u003cli\u003eIncludes five extension rods to span the full measurement range\u003c\/li\u003e\n  \u003cli\u003eSupplied with a calibration standard for micrometer head verification\u003c\/li\u003e\n  \u003cli\u003eShips pre-calibrated from the factory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standalone inside tubular micrometer for general-purpose internal diameter measurement in industrial and precision machining applications.

Handle with care to avoid dropping or impacting the measuring faces or extension rods, as contact damage will affect accuracy. Verify calibration against the included standard before use and periodically during extended measurement sessions. Store in the provided case when not in use to protect the carbide faces and extension rods from contamination and mechanical damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Range\u003c\/strong\u003e: 2 to 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Friction\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Face Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Extension Rods\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCalibrated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDigital Counter\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111601\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MS160712028\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51715646456114,"sku":"MS160712028","price":255.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c8cac4a70099fd991b85179c0c8e1275.jpg?v=1788516747","url":"https:\/\/voomisupply.com\/products\/spi-ms160712028-inside-tubular-micrometer-2-12-in","provider":"Voomi Supply","version":"1.0","type":"link"}
