It covers a full 6-inch measurement range using a set of six interchangeable rods, each with a 3\/16-inch (0.1719-inch decimal) diameter. The instrument reads to a graduation of 0.001 inches with an accuracy of 0.0002 inches. A ratchet stop thimble delivers consistent measuring pressure across readings, reducing operator-to-operator variation. The 2.5-inch base is hardened and ground for flat, stable contact against the workpiece surface. Finished in satin chrome to minimize glare, this micrometer is suited for use in shop-floor and inspection environments.\u003c\/p\u003e\u003cp\u003eThis depth micrometer is used wherever accurate depth readings are required: measuring slot depths, counterbore depths, step heights, and shoulder dimensions on machined parts. The six-rod set allows coverage from zero to 6 inches without switching instruments. It is commonly used by machinists, tool and die makers, quality control technicians, and precision measurement professionals working in manufacturing, job shops, and inspection departments. The included case keeps the rods and base organized and protected when not in use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e6-inch maximum measurement range with six interchangeable rods\u003c\/li\u003e\n\u003cli\u003e0.001-inch graduation for precise depth readings\u003c\/li\u003e\n\u003cli\u003e0.0002-inch accuracy for reliable inspection-grade measurement\u003c\/li\u003e\n\u003cli\u003eRatchet stop thimble ensures consistent, repeatable measuring force\u003c\/li\u003e\n\u003cli\u003e2.5-inch base surface is hardened and ground for stable contact\u003c\/li\u003e\n\u003cli\u003eLocking clamp holds the reading for transfer to a reference scale\u003c\/li\u003e\n\u003cli\u003eSatin chrome finish reduces glare in bright shop lighting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard mechanical depth micrometer for general-purpose precision measurement; compatible with any application requiring depth readings up to 6 inches using 3\/16-inch diameter rods.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDepth micrometers are installed by metrology and quality control personnel and do not require power or mechanical fastening. Before use, verify the base and rod contact surfaces are clean and free of chips or burrs that could affect zero calibration. Set and verify zero with all rods seated fully before taking measurements. Store rods in the provided case to prevent damage to the ground surfaces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Measurement Range\u003c\/strong\u003e: 6 inches\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: 0.0002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Ratchet Stop\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRod Diameter\u003c\/strong\u003e: 0.1719 inches (3\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Rods\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Satin Chrome\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Surface\u003c\/strong\u003e: Hardened and Ground\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Case\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.95 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111601\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: 52-225-112-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FOWLER","offers":[{"title":"Default Title","offer_id":67912962048306,"sku":"52-225-112-0","price":338.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/80b0dce28d0f238cc6ebde5e60404c48.jpg?v=1791241154","url":"https:\/\/voomisupply.com\/products\/fowler-52-225-112-0-mechanical-depth-micrometer-6-in","provider":"Voomi Supply","version":"1.0","type":"link"}
