It covers a measurement range of 0 to 1 inch with a graduation of 0.001 inches and an accuracy of 0.0001 inches. The friction thimble delivers consistent, repeatable gauging force so readings are not affected by operator variation. Solid carbide measuring faces resist wear under regular shop use. A positive lever locking clamp secures the spindle in place for reliable measurement transfer. This instrument is suited for machinists, tool and die technicians, and precision measurement professionals.\u003c\/p\u003e\u003cp\u003eThe 52-253-001-1 is used wherever tight-tolerance outside diameter, thickness, or width measurements are required. Typical applications include inspecting turned parts, bar stock, sheet metal, and machined components in job shops, manufacturing facilities, and tool rooms. The non-rotating spindle prevents surface marking on finished workpieces. The included case and wrench support clean storage and routine calibration adjustments in field and bench settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 inch measurement range with 0.001 inch graduation for fine linear readings\u003c\/li\u003e\n\u003cli\u003eAccuracy of 0.0001 inches for tight-tolerance inspection work\u003c\/li\u003e\n\u003cli\u003eFriction thimble provides consistent gauging pressure and repeatable results\u003c\/li\u003e\n\u003cli\u003eSolid carbide measuring faces for extended wear life in production environments\u003c\/li\u003e\n\u003cli\u003ePositive lever locking clamp secures spindle position during measurement transfer\u003c\/li\u003e\n\u003cli\u003eNon-rotating spindle protects delicate or finished workpiece surfaces\u003c\/li\u003e\n\u003cli\u003eIncludes protective storage case and adjustment wrench\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 0 to 1 inch range outside micrometer suitable for general-purpose precision measurement in machining and inspection workflows.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eOutside micrometers require no installation but should be calibrated against a known standard or gauge block before use. Handle measuring faces with care and avoid contact with abrasive surfaces. Store the instrument in the included case when not in use to protect the faces and thimble mechanism. Calibration and maintenance should be performed by a qualified metrologist or toolroom technician in accordance with applicable shop quality standards.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 0 to 1 inch\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: 0.0001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Friction\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasuring Face Material\u003c\/strong\u003e: Solid Carbide\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\u003eWeight\u003c\/strong\u003e: 0.6 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Case, Wrench\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 52-253-001-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FOWLER","offers":[{"title":"Default Title","offer_id":67906201911602,"sku":"52-253-001-1","price":81.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02e3ff1c16d4dcb1322756c20b3965fd.jpg?v=1791166048","url":"https:\/\/voomisupply.com\/products\/fowler-52-253-001-1-mechanical-outside-micrometer","provider":"Voomi Supply","version":"1.0","type":"link"}
