It features a ratchet stop thimble that delivers consistent measuring force and helps eliminate operator-induced error. Graduation is 0.001 inches with an accuracy of plus or minus 0.0002 inches, making it well suited for quality control and inspection work where tight tolerances are required. The micrometer ships NIST traceable with a short-form certificate of calibration included. A painted finish provides corrosion resistance in shop environments. Machinists, metrologists, and QC inspectors are the primary users of this instrument.\u003c\/p\u003e\u003cp\u003eThis micrometer is used in precision machining, thread inspection, and quality assurance applications where screw thread form and pitch diameter must be verified within close tolerances. The interchangeable anvil design allows the same frame to be configured for multiple thread forms and pitch ranges, increasing versatility across a tool crib or inspection department. It is appropriate for both production floor use and controlled metrology environments. The included case protects the instrument during storage and transport between job sites or inspection stations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMeasurement range: 3.0000 to 4.0000 inches\u003c\/li\u003e\n\u003cli\u003eGraduation of 0.001 inches with accuracy of plus or minus 0.0002 inches\u003c\/li\u003e\n\u003cli\u003eRatchet stop thimble for repeatable, consistent measuring force\u003c\/li\u003e\n\u003cli\u003eInterchangeable anvils for flexibility across thread forms and pitches\u003c\/li\u003e\n\u003cli\u003eNIST traceable calibration with short-form certificate of calibration included\u003c\/li\u003e\n\u003cli\u003eIncludes protective carrying case and standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style precision measuring instrument for mechanical screw thread inspection applications in the 3 to 4 inch range; verify anvil compatibility with the specific thread form and pitch before use.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis instrument is a handheld precision measuring tool, not an installed component. Handle with clean, dry hands or cotton inspection gloves to prevent thermal expansion from body heat affecting readings. Store in the included case when not in use and keep away from magnetic fields, extreme temperatures, and abrasive environments. Calibration should be verified against known standards before use in a critical inspection process, consistent with ISO 9001 and similar quality system requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Measurement\u003c\/strong\u003e: 3.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 4.0000 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: plus or minus 0.0002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResolution\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Mechanical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Ratchet Stop\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnvil Type\u003c\/strong\u003e: Interchangeable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Painted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTraceability Certification\u003c\/strong\u003e: NIST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 11.82 inches (L) x 6.5 inches (W) x 1.82 inches (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.79 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Carrying Case, Short Form Certificate of Calibration, Standards\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: CMS160726112\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51695673344306,"sku":"CMS160726112","price":233.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0442c41c312088dd0213b487d136e55.jpg?v=1788337326","url":"https:\/\/voomisupply.com\/products\/spi-cms160726112-screw-thread-micrometer-3-to-4-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
