It covers a measurement range of 3 inches with a graduation of 0.0001 inches and an accuracy of 0.00023 inches, making it suitable for close-tolerance work where consistent repeatability is critical. The ratchet stop thimble controls applied measuring pressure, reducing operator-to-operator variation. Solid carbide measuring faces provide long-term wear resistance. A quick-zero adjustment on the sleeve allows fast calibration without specialized tooling. This instrument is used by machinists, quality control technicians, and precision tradespeople who require reliable hand-tool measurement.\u003c\/p\u003e\n\u003cp\u003eThe 52-240-003-1 is appropriate for general-purpose outside diameter and thickness measurement across metalworking, mechanical assembly, and inspection applications. It suits both shop-floor use and bench inspection tasks. The fixed non-rotating spindle design keeps the measuring faces properly oriented throughout the stroke. The included case and sleeve wrench support proper storage and field calibration. This micrometer fits workflows where a digital readout is not required and a durable mechanical instrument is preferred.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-inch measurement range with 0.0001-inch graduation for precise readings\u003c\/li\u003e\n  \u003cli\u003eAccuracy of 0.00023 inches supports close-tolerance inspection work\u003c\/li\u003e\n  \u003cli\u003eRatchet stop thimble standardizes measuring force across operators\u003c\/li\u003e\n  \u003cli\u003eSolid carbide measuring faces resist wear for extended service life\u003c\/li\u003e\n  \u003cli\u003eQuick, easy zero adjustment on sleeve for fast field calibration\u003c\/li\u003e\n  \u003cli\u003eNon-rotating spindle maintains consistent face alignment during measurement\u003c\/li\u003e\n  \u003cli\u003eIncludes protective case and sleeve wrench\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose outside micrometer suitable for standard metalworking, fabrication, and precision inspection applications requiring a 3-inch range mechanical instrument.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis instrument is used by machinists, metrologists, and precision tradespeople and requires no power source or installation. Before use, verify zero calibration with the included sleeve wrench and store the micrometer in its case when not in service to protect the measuring faces. Avoid dropping or impacting the instrument, as this can affect calibration and spindle alignment. Periodic cleaning of the spindle threads and measuring faces with a lint-free cloth is recommended to maintain accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement Range\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\u003eAccuracy\u003c\/strong\u003e: 0.00023 inches\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDigital Counter\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Face Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Case, Sleeve Wrench\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: FOWLER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 52-240-003-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FOWLER","offers":[{"title":"Default Title","offer_id":67912952316210,"sku":"52-240-003-1","price":92.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3e231b446e4acc46f9e02088fa55e78.jpg?v=1791241070","url":"https:\/\/voomisupply.com\/products\/fowler-52-240-003-1-outside-micrometer-3-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
