It covers an 11-inch measurement range with a graduation of 0.0001 inches and an accuracy of 0.0001 inches, making it suitable for high-tolerance inspection work. The ratchet stop thimble provides consistent measuring pressure to reduce operator-to-operator variation. Solid carbide measuring faces resist wear over extended use. A ring-style lock nut secures the spindle position once a reading is taken. This tool is used by machinists, metrology technicians, and quality control professionals in production and inspection environments.\u003c\/p\u003e\n\u003cp\u003eThe STARRETT 72738 is suited for shop-floor and inspection-room applications where large-diameter or long workpieces require outside measurement beyond standard 1-inch or 6-inch micrometer ranges. Its 11-inch capacity accommodates shafts, cylinders, and machined components common in heavy manufacturing, tooling, and precision fabrication. The satin chrome finish reduces glare under shop lighting. A lock nut and wrench are included for immediate use out of the box.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e11-inch maximum measurement range for large workpieces\u003c\/li\u003e\n  \u003cli\u003e0.0001-inch graduation and 0.0001-inch accuracy for high-tolerance readings\u003c\/li\u003e\n  \u003cli\u003eRatchet stop thimble delivers consistent, repeatable measuring pressure\u003c\/li\u003e\n  \u003cli\u003eSolid carbide measuring faces on both anvil and spindle for extended wear life\u003c\/li\u003e\n  \u003cli\u003eRing-style lock nut with included wrench for secure spindle locking\u003c\/li\u003e\n  \u003cli\u003eSatin chrome finish minimizes glare in bright work environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard outside micrometer for use in any application requiring mechanical measurement of external dimensions up to 11 inches.

Store in the supplied case or a protected location away from temperature extremes to maintain calibration. Clean measuring faces with a lint-free cloth before and after use. Do not overtighten the lock nut, as this can stress the frame and affect accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 11 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: 0.300 inches (7.60 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle Diameter\u003c\/strong\u003e: 0.300 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\u003eCoating\/Finish\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: 3 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: 72738\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540149272882,"sku":"72738","price":601.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f76b415c6df8b6ea6b7b5fbb89329400.jpg?v=1785847152","url":"https:\/\/voomisupply.com\/products\/starrett-72738-mechanical-outside-micrometer-11-in","provider":"Voomi Supply","version":"1.0","type":"link"}
