It extends the measuring range of compatible depth gages to cover depths from 4 to 5 inches. The rod features a 5\/32-inch diameter (3.20 mm) and is engineered to the dimensional tolerances required for accurate micrometer-grade depth measurement. Metrology technicians, machinists, and quality control professionals install this rod when extending or restoring the measurement range of a depth gage set. It ships individually and is sold as a single unit.\u003c\/p\u003e\n\u003cp\u003eThis rod is suited for dimensional inspection tasks in machine shops, toolrooms, and manufacturing quality control environments. It is used wherever a 443 or 445 Series Starrett micrometer depth gage requires a 4-to-5-inch measurement range extension. Applications include measuring slot depths, counterbore depths, and step heights on machined components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasurement range: 4 to 5 inches when used with a compatible depth gage\u003c\/li\u003e\n  \u003cli\u003eRod diameter: 5\/32 inch (3.20 mm) for proper fit in 443 and 445 Series gage bodies\u003c\/li\u003e\n  \u003cli\u003eDesigned as a direct OEM accessory replacement rod\u003c\/li\u003e\n  \u003cli\u003eSold as a single rod (package quantity: 1)\u003c\/li\u003e\n  \u003cli\u003eLightweight construction at 0.0375 pounds for easy handling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with the Starrett 443 and 445 Series micrometer depth gages, as specified in the product documentation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified metrologist or machinist familiar with micrometer depth gage assembly. Before swapping rods, ensure the gage is clean and free of debris at the spindle and rod-seating surfaces. Handle the rod only at non-measuring surfaces to avoid introducing measurement error from contamination or thermal expansion. After installation, verify zero calibration against a known reference standard before returning the gage to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccessory Type\u003c\/strong\u003e: Rod\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 4 to 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 5.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRod Diameter\u003c\/strong\u003e: 5\/32 inch (3.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAnvil Type\u003c\/strong\u003e: Rod\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0375 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 71986\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51539081134386,"sku":"71986","price":37.8,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b6cfb5721d6e6d9279969575c43ef7d1.jpg?v=1785834554","url":"https:\/\/voomisupply.com\/products\/starrett-71986-micrometer-rod-4-to-5-inches-depth-gage","provider":"Voomi Supply","version":"1.0","type":"link"}
