It delivers an accuracy of 0.0001 inches and features a ratchet stop thimble for consistent, repeatable measuring pressure on every reading. Measuring faces are solid carbide for long-term wear resistance in shop environments. A ring-style lock nut holds the spindle position during transfer measurements. This tool is used by machinists, tool-and-die workers, and quality-control technicians who require reliable precision in manual inspection work.\u003c\/p\u003e\n\u003cp\u003eThe 72734 is suited for outside diameter and flat-surface measurements on machined components, shafts, castings, and similar workpieces up to 7 inches. The hammertone baked enamel frame finish provides corrosion resistance in typical shop conditions. The ratchet stop thimble mechanism allows the user to apply uniform measuring force without over-tightening, which is critical when working to tolerances in the 0.0001-inch range. It ships with a lock nut and wrench included.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7-inch maximum measurement range with 0.0001-inch graduation and 0.0001-inch accuracy\u003c\/li\u003e\n  \u003cli\u003eRatchet stop thimble for consistent, repeatable measuring force\u003c\/li\u003e\n  \u003cli\u003eSolid carbide measuring faces for extended wear life\u003c\/li\u003e\n  \u003cli\u003eRing-type lock nut included for spindle position hold\u003c\/li\u003e\n  \u003cli\u003eFlat anvil and 0.3-inch anvil and spindle diameter\u003c\/li\u003e\n  \u003cli\u003eHammertone baked enamel frame finish for corrosion resistance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style precision outside micrometer for manual dimensional inspection applications requiring a 7-inch measurement range.

Before use, clean the anvil and spindle faces and verify zero calibration with a reference standard appropriate to the measurement range. The lock nut and wrench provided should be used to secure the thimble position when transferring measurements. Store in a protective case away from heat sources and corrosive materials to preserve calibration integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement Range\u003c\/strong\u003e: 7 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\u003eThimble Type\u003c\/strong\u003e: Ratchet Stop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAnvil Type\u003c\/strong\u003e: Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Face Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAnvil Diameter\u003c\/strong\u003e: 0.3 inches (7.60 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle Diameter\u003c\/strong\u003e: 0.3 inches (7.60 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Nut Type\u003c\/strong\u003e: Ring\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\u003eFrame Finish\u003c\/strong\u003e: Hammertone Baked Enamel\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: 5.438 pounds\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: 72734\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540514996530,"sku":"72734","price":493.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/900882578aec5912660ac37bd4457bd6.jpg?v=1785857134","url":"https:\/\/voomisupply.com\/products\/starrett-72734-mechanical-outside-micrometer-7-in-range","provider":"Voomi Supply","version":"1.0","type":"link"}
