It covers a measurement range of 0 to 4 inches with a graduation of 0.0001 inches and an accuracy of 0.0002 inches. The ratchet stop thimble provides consistent measuring pressure, reducing operator-to-operator variation. Measuring faces are solid carbide for extended wear resistance. The unit ships calibrated and includes a NIST traceability certificate, making it ready for use in quality-controlled environments. Machinists, tool-and-die technicians, and metrology professionals are the primary users of this instrument.\u003c\/p\u003e\n\u003cp\u003eThis outside micrometer is suited for precision inspection and dimensional verification of cylindrical and flat workpieces in job shops, production floors, and quality labs. The rotating spindle and ratchet stop thimble support repeatable measurements across extended use. It is packaged with a protective case and a short-form certificate of calibration with NIST traceability standards, making it appropriate for ISO-compliant and regulated inspection environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasurement range of 0 to 4 inches with 0.0001 inch graduation\u003c\/li\u003e\n  \u003cli\u003eAccuracy of 0.0002 inches for high-precision dimensional inspection\u003c\/li\u003e\n  \u003cli\u003eRatchet stop thimble ensures consistent, repeatable measuring pressure\u003c\/li\u003e\n  \u003cli\u003eSolid carbide measuring faces resist wear for long service life\u003c\/li\u003e\n  \u003cli\u003eRotating spindle with 0.25 inch spindle diameter\u003c\/li\u003e\n  \u003cli\u003eShips calibrated with NIST traceability certificate and protective case\u003c\/li\u003e\n  \u003cli\u003eHammertone and baked enamel coating for corrosion resistance and durability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose mechanical outside micrometer for precision measurement of external dimensions on machined parts and workpieces up to 4 inches in diameter or thickness.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis instrument requires no installation but should be handled and stored by trained metrology or machining personnel following established gauge-handling procedures. Before use, verify the zero setting against the supplied calibration standards and store the micrometer in the included protective case when not in use. Avoid dropping or exposing the instrument to excessive heat, as this can affect calibration. Periodic recalibration against NIST-traceable standards is recommended to maintain measurement accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 0 to 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation\u003c\/strong\u003e: 0.0001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Ratchet Stop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Face Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Hammertone and Baked Enamel\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\u003eIncludes\u003c\/strong\u003e: Case, Short Form Certificate of Calibration, Standards\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 9.65 inches L x 5.12 inches W x 1.23 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.73 pounds\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: CMS161205005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51702571270450,"sku":"CMS161205005","price":78.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/611a1db642f6fab7e1d148199803db19.jpg?v=1788412034","url":"https:\/\/voomisupply.com\/products\/spi-cms161205005-outside-micrometer-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
