It delivers a measurement range of 1 inch with a graduation of 0.0001 inches and an accuracy of 0.000050 inches, making it suitable for close-tolerance inspection work in machining, manufacturing, and metrology applications. The micrometer features a friction thimble for consistent measuring force and a satin chrome finish that reduces glare during use. Measuring faces are solid carbide for long-term wear resistance. A ring-style lock nut secures the spindle position once a measurement is taken. Machinists, quality control technicians, and tool-and-die professionals are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis micrometer is suited for shop-floor and inspection-room use where repeatable, high-accuracy outside measurements are required. Typical applications include checking shaft diameters, tool stock, and machined part dimensions in both production and job-shop environments. The flat anvil configuration accommodates a wide range of workpiece geometries. The included lock nut and wrench support secure readings during recording or comparison work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1 inch measurement range with 0.0001 inch graduation for fine-resolution readings\u003c\/li\u003e\n  \u003cli\u003eAccuracy of 0.000050 inches for close-tolerance inspection\u003c\/li\u003e\n  \u003cli\u003eSolid carbide measuring faces for extended wear life\u003c\/li\u003e\n  \u003cli\u003eFriction thimble provides consistent, repeatable measuring force\u003c\/li\u003e\n  \u003cli\u003eRing-style lock nut holds spindle position during measurement recording\u003c\/li\u003e\n  \u003cli\u003eSatin chrome finish reduces reflective glare in bright shop environments\u003c\/li\u003e\n  \u003cli\u003eIncludes lock nut and wrench for field adjustments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard outside micrometer for general mechanical measurement tasks requiring a 0 to 1 inch range and 0.0001 inch graduation resolution.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eOutside micrometers require no installation, but should be cleaned and zeroed against a calibration standard before use. Store the micrometer with the anvil and spindle faces slightly separated to prevent thermal expansion damage. Calibration and verification should be performed by a qualified metrologist or toolroom technician in accordance with applicable metrology standards. Avoid dropping or impacting the instrument, as this can affect calibration.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement Range\u003c\/strong\u003e: 1 inch\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: 0.000050 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAnvil Type\u003c\/strong\u003e: Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAnvil Diameter\u003c\/strong\u003e: 0.235 inches (6.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Friction\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\u003eFinish\u003c\/strong\u003e: Satin Chrome\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Lock Nut, Wrench\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\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: 50947\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541425029426,"sku":"50947","price":363.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/100c03e926184a08eb977f0de83d1655.jpg?v=1785875745","url":"https:\/\/voomisupply.com\/products\/starrett-50947-mechanical-outside-micrometer-1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
