It covers a measurement range of 0.1200 to 0.1600 inches and delivers an accuracy of 0.0001 inches with a graduation of 0.0001 inches. The instrument features carbide measuring surfaces for durability and a ratchet stop thimble for consistent gauging pressure on every measurement. It ships with a NIST traceability certification, making it suitable for calibrated inspection work in shops, maintenance environments, and quality control applications.\u003c\/p\u003e\u003cp\u003eThis hole micrometer is used in precision machining, tool and die, maintenance and repair operations, and quality inspection settings where small internal bore diameters must be confirmed to close tolerances. The self-centering contact points align the instrument automatically within the bore, reducing operator error. A setting ring with a diameter of 0.1600 inches is included for field zeroing and verification. The chrome finish resists corrosion during regular shop use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMeasurement range of 0.1200 to 0.1600 inches for small internal bores\u003c\/li\u003e\n\u003cli\u003eAccuracy of 0.0001 inches with 0.0001-inch graduation\u003c\/li\u003e\n\u003cli\u003eCarbide measuring surfaces for extended wear resistance\u003c\/li\u003e\n\u003cli\u003eRatchet stop thimble for repeatable, consistent gauging pressure\u003c\/li\u003e\n\u003cli\u003eSelf-centering two-point contact for accurate bore alignment\u003c\/li\u003e\n\u003cli\u003eNIST traceability certification included for calibrated inspection compliance\u003c\/li\u003e\n\u003cli\u003eOne setting ring included for field zeroing and verification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style precision measurement instrument for use in any shop or inspection environment requiring internal bore measurement in the 0.1200 to 0.1600 inch range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis instrument is used by machinists, tool and die makers, and quality control technicians. Before use, zero the micrometer against the included setting ring following the manufacturer's calibration procedure. Clean the measuring surfaces and bore thoroughly before gauging to avoid false readings. Store in the provided case to protect the carbide contact points and maintain calibration integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMicrometer Type\u003c\/strong\u003e: Hole\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Measurement\u003c\/strong\u003e: 0.1200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 0.1600 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy (Inch)\u003c\/strong\u003e: 0.0001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy (mm)\u003c\/strong\u003e: 0.002 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGraduation (Inch)\u003c\/strong\u003e: 0.0001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGage Depth\u003c\/strong\u003e: 0.8900 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSetting Ring Diameter\u003c\/strong\u003e: 0.1600 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Contact Points\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Setting Rings Included\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Ratchet Stop\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Chrome\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCalibrated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTraceability Certification\u003c\/strong\u003e: NIST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions\u003c\/strong\u003e: 6.5 inches L x 5.8 inches W x 2.29 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.9 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: MS160712141\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51695765553458,"sku":"MS160712141","price":431.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b6ea619ed1aac7ace5ce924af3eac2b.jpg?v=1788338107","url":"https:\/\/voomisupply.com\/products\/spi-ms160712141-hole-micrometer-0-1200-0-1600-in","provider":"Voomi Supply","version":"1.0","type":"link"}
