It covers a measurement range up to 4 inches with a graduation of 0.0001 inches and an accuracy of 0.0001 inches, making it suitable for close-tolerance work where reliable repeatability matters. The thimble uses a ratchet stop mechanism to deliver consistent measuring force across readings, and the rotating spindle aids in smooth, accurate contact. Measuring faces are solid carbide for wear resistance under repeated use. This tool is used by machinists, toolmakers, quality control technicians, and skilled tradespeople who require verified dimensional accuracy.\u003c\/p\u003e\n\u003cp\u003eThe T444.1XRL-4 is appropriate for precision measurement tasks in machine shops, manufacturing facilities, and field inspection environments. It handles external diameter, thickness, and length measurements on metal, plastic, and other solid materials up to 4 inches. The satin chrome finish reduces glare during use. A ring-style lock nut holds the spindle in position once a measurement is set. The micrometer ships with a protective case and a wrench, giving the user everything needed to put it into service immediately.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasurement range up to 4 inches with 0.0001 inch graduation\u003c\/li\u003e\n  \u003cli\u003eAccuracy of 0.0001 inches for close-tolerance inspection work\u003c\/li\u003e\n  \u003cli\u003eRatchet stop thimble ensures consistent measuring force across readings\u003c\/li\u003e\n  \u003cli\u003eRotating spindle for smooth, precise contact with workpiece\u003c\/li\u003e\n  \u003cli\u003eSolid carbide measuring faces resist wear over extended service life\u003c\/li\u003e\n  \u003cli\u003eRing lock nut secures spindle position when recording or transferring measurements\u003c\/li\u003e\n  \u003cli\u003eIncludes protective case and wrench\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a precision outside micrometer for general mechanical measurement applications requiring a 4-inch range and 0.0001 inch resolution.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNo power source or wiring is required for this mechanical instrument. Before use, verify the micrometer reads zero at its reference point and use the included wrench to adjust the anvil if calibration is needed. Store the instrument in the included case when not in use to protect the carbide measuring faces and maintain calibration. Handle with clean, dry hands or inspection gloves to prevent corrosion from skin contact.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement Range\u003c\/strong\u003e: 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: 0.0001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAnvil Type\u003c\/strong\u003e: Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Ratchet Stop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRotating Spindle\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\u003eLock Nut Type\u003c\/strong\u003e: Ring\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: Satin Chrome\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 9.8 inches (L) x 5 inches (W) x 1.8 inches (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Case, Wrench\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: California Proposition 65\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: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: T444.1XRL-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542872162610,"sku":"T444.1XRL-4","price":287.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0d35a8e289c49382e6fc133aa36b7ea2.jpg?v=1785909462","url":"https:\/\/voomisupply.com\/products\/starrett-t444-1xrl-4-outside-micrometer-4-in-range","provider":"Voomi Supply","version":"1.0","type":"link"}
