It covers a measurement range of 6 inches using a set of 6 interchangeable rotating rods, each with a diameter of 0.176 inches (3\/16 inch nominal). Graduation is 0.0001 inches with an accuracy rating of 0.0002 inches, making it well-suited for applications where close tolerance verification is required. The ratchet stop thimble provides consistent measuring pressure, and the satin chrome finish reduces glare during use. Machinists, tool and die makers, and quality control technicians are the primary users of this instrument.\u003c\/p\u003e\n\u003cp\u003eThis depth micrometer is used in metalworking shops, manufacturing facilities, and inspection departments for measuring the depth of slots, holes, counterbores, and shoulders. The 4-inch base length provides a stable reference surface across a range of workpiece configurations. The base surface is hardened and ground for flatness and wear resistance. The included wooden case keeps the rods organized and protects the instrument during storage and transport. It is appropriate for both bench use and in-process inspection on the shop floor.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-inch total measurement range with 6 interchangeable rotating rods\u003c\/li\u003e\n  \u003cli\u003e0.0001-inch graduation for fine resolution depth readings\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch accuracy rating for close tolerance inspection work\u003c\/li\u003e\n  \u003cli\u003eRatchet stop thimble ensures repeatable, consistent measuring pressure\u003c\/li\u003e\n  \u003cli\u003e4-inch hardened and ground base surface for stable seating on workpieces\u003c\/li\u003e\n  \u003cli\u003eLocking clamp holds the reading for transfer measurement\u003c\/li\u003e\n  \u003cli\u003eIncludes wooden storage and transport case\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard mechanical depth micrometer for general-purpose depth measurement tasks in machining and inspection environments where a 6-inch range and interchangeable rod system are required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis instrument requires no installation but should be handled and stored by a qualified machinist or metrologist familiar with micrometer calibration and care. Before use, clean the base surface and rod measuring faces with a lint-free cloth and verify the zero setting with the shortest rod seated. Do not overtighten the locking clamp, as this can affect calibration. Periodic calibration against a certified gage block set is recommended to verify accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 0.0001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Rods\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRod Type\u003c\/strong\u003e: Rotating, interchangeable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRod Diameter\u003c\/strong\u003e: 0.176 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Length\u003c\/strong\u003e: 4 inches\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: Hardened Steel\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: Wooden Case\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111601\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: FOWLER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 52-225-116-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FOWLER","offers":[{"title":"Default Title","offer_id":67913592832306,"sku":"52-225-116-0","price":336.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aea8eb3740e9b5e57e3557ab311f9803.jpg?v=1791246201","url":"https:\/\/voomisupply.com\/products\/fowler-52-225-116-0-mechanical-depth-micrometer-6-in","provider":"Voomi Supply","version":"1.0","type":"link"}
