It covers a measurement range of 2 to 3 inches with a graduation of 0.0001 inches, making it well suited for inspecting external screw threads on fasteners, threaded shafts, and machined components. The digital readout includes a built-in digital counter and data output capability, allowing measurements to be recorded or transferred directly to a quality management system. Interchangeable stainless steel anvils and a rotating spindle provide versatility across different thread forms. A ratchet thimble ensures consistent measuring force on every use.\u003c\/p\u003e\u003cp\u003eThis micrometer is used in precision machining, manufacturing inspection, and quality control environments where thread dimensions must be verified to tight tolerances. It is appropriate for shops working with inch-series threaded parts in the 2 to 3 inch diameter range. The instrument meets ASME B89.1.13 standards, confirming it is built and calibrated to recognized metrology industry requirements. It ships in a plastic storage box and arrives factory calibrated. Typical users include machinists, quality control technicians, and toolroom professionals.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eElectronic operation with digital counter and 0.0001 inch graduation for high-resolution thread measurement\u003c\/li\u003e\n\u003cli\u003eMeasurement range of 2 to 3 inches covers larger-diameter threaded components\u003c\/li\u003e\n\u003cli\u003eInterchangeable stainless steel anvils accommodate different thread forms\u003c\/li\u003e\n\u003cli\u003eRatchet thimble provides repeatable, consistent measuring force\u003c\/li\u003e\n\u003cli\u003eData output port allows direct integration with SPC or quality recording systems\u003c\/li\u003e\n\u003cli\u003eFactory calibrated and compliant with ASME B89.1.13 metrology standard\u003c\/li\u003e\n\u003cli\u003ePositive lock nut secures the spindle for stable reference readings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style precision instrument for measuring external screw thread pitch diameters on inch-series threaded components in the 2 to 3 inch range. Interchangeable anvils are not included and must be sourced separately to match specific thread forms.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis instrument is handled and used by metrology technicians, machinists, and quality control personnel rather than installed in a system. Before use, verify calibration status and clean all contact surfaces with a lint-free cloth. Store in the included plastic box when not in use to protect the measuring faces and digital components. Do not expose the instrument to cutting fluids, magnetic fields, or impact that could affect accuracy or the electronic components.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Electronic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Measurement\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGraduation\u003c\/strong\u003e: 0.0001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnvil Type\u003c\/strong\u003e: Interchangeable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnvil Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpindle Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpindle Diameter\u003c\/strong\u003e: 6.50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Ratchet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLock Nut Type\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDigital Counter\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eData Output\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotating Spindle\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCalibrated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Plastic Box\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B89.1.13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.97 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.23 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: CMS220519014\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51710665851186,"sku":"CMS220519014","price":400.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8bb8a45ec049f2b46c731aad7327100e_8ad0dc37-bec0-4efa-bdb7-6c3e0a6d7b57.jpg?v=1788469266","url":"https:\/\/voomisupply.com\/products\/spi-cms220519014-electronic-screw-thread-micrometer","provider":"Voomi Supply","version":"1.0","type":"link"}
