It extends the measurement range from 5 to 6 inches, allowing technicians and machinists to reach deeper workpiece features without switching instruments. The rod measures 5\/32 inch (3.20 mm) in diameter and is machined to maintain the precision tolerances required for accurate depth measurement. This type of accessory rod is a standard replacement and range-extension component used in metrology, fabrication, and quality-control settings. Installation requires no special tools and is handled by machinists, tool and die workers, or QC technicians.\u003c\/p\u003e\n\u003cp\u003eThis rod is used in conjunction with STARRETT 443 and 445 Series micrometer depth gages in production, inspection, and machining environments. It is appropriate for both shop-floor measurement and bench-level inspection work where depth readings in the 5 to 6 inch range are required. The rod-style anvil design is suited for measuring slots, bores, shoulders, and recesses where a flat anvil would not seat properly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExtends measurement range to 5 to 6 inches on compatible depth gages\u003c\/li\u003e\n  \u003cli\u003eRod diameter of 5\/32 inch (3.20 mm) for precise fitment\u003c\/li\u003e\n  \u003cli\u003eRod-type anvil design suited for slots, bores, and recessed features\u003c\/li\u003e\n  \u003cli\u003eDirect OEM-style replacement accessory for 443 and 445 Series gages\u003c\/li\u003e\n  \u003cli\u003eSold individually — package quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with STARRETT 443 and 445 Series micrometer depth gages, as specified by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or metrology technicians familiar with micrometer depth gage accessories. Thread or seat the rod into the gage spindle according to the gage manufacturer instructions, ensuring the rod is fully engaged and seated before taking measurements. Handle the rod with care to avoid nicks or burrs on the contact surfaces, which can affect measurement accuracy. Verify calibration of the assembled gage before use in critical inspection work.\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: 5 to 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 6.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAnvil Type\u003c\/strong\u003e: Rod\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\u003eWeight\u003c\/strong\u003e: 0.033 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: 71987\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544551227698,"sku":"71987","price":37.8,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6ab49c2cd52c643769590460cfa1abb9.jpg?v=1785929630","url":"https:\/\/voomisupply.com\/products\/starrett-71987-micrometer-extension-rod-5-to-6-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
