Built for precision dimensional measurement in heavy industrial and manufacturing environments, this set features a ratchet stop thimble for consistent measuring pressure and steel measuring faces for durability under repeated use. The satin chrome finish reduces glare during use. These micrometers are designed for machinists, toolmakers, and metrology technicians who require accurate large-bore and large-diameter measurement on the shop floor or inspection bench.\u003c\/p\u003e\n\u003cp\u003eThis set is suited for large-scale precision work such as measuring shafts, cylinders, bores, and machined components that fall in the 20 to 24 inch range. Each micrometer in the set covers one inch of that range, with individual units corresponding to the 20, 21, 22, and 23 inch measurement standards. The set ships in a protective case, keeping each instrument organized and protected between uses. Typical users include tool and die shops, aerospace and heavy equipment fabrication facilities, and industrial inspection departments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-piece set covers 20 to 24 inches in 1-inch increments\u003c\/li\u003e\n  \u003cli\u003eRatchet stop thimble delivers repeatable, consistent measuring pressure\u003c\/li\u003e\n  \u003cli\u003eSteel measuring faces resist wear during high-frequency use\u003c\/li\u003e\n  \u003cli\u003eSatin chrome finish minimizes glare and corrosion\u003c\/li\u003e\n  \u003cli\u003eIncludes protective storage case for all four micrometers\u003c\/li\u003e\n  \u003cli\u003eNon-rotating spindle design maintains measurement stability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for large-diameter outside measurement applications requiring precision instruments in the 20 to 24 inch range.

Before use, verify calibration against the included standards and allow the instrument to thermally stabilize in the measurement environment. Do not use excessive force when closing the thimble; always use the ratchet stop to apply consistent pressure. Store each micrometer in the provided case when not in use to protect the measuring faces and spindle threads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Measurement\u003c\/strong\u003e: 20 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 24 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Ratchet Stop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Face Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRotating Spindle\u003c\/strong\u003e: No\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: Case\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards Included\u003c\/strong\u003e: 20, 21, 22, 23 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 19 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: 72705\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51543583883570,"sku":"72705","price":2188.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7759dbd237843de654d61aa617472686.jpg?v=1785920688","url":"https:\/\/voomisupply.com\/products\/starrett-72705-outside-micrometer-set-20-24-in-4-pc","provider":"Voomi Supply","version":"1.0","type":"link"}
