It extends the measurement range of compatible depth gages to cover the 6 to 7 inch range, making it an essential accessory for dimensional inspection work in machining, fabrication, and quality control environments. The rod measures 5\/32 inch (3.20 mm) in diameter and is precision-manufactured to maintain the accuracy expected from depth gage accessories used in close-tolerance measurement applications. Machinists and metrology technicians are the primary users of this component.\u003c\/p\u003e\n\u003cp\u003eThis rod is intended for professional measurement environments where depth gage range must be extended to accommodate deeper bores, slots, or stepped features. The 443 and 445 Series micrometer depth gages are commonly found in machine shops, tool rooms, and production inspection stations. The 71988 rod slots into the existing gage body and allows the technician to reach measurement depths between 6 and 7 inches without switching instruments. It ships as a single rod, sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExtends measurement range to cover 6 to 7 inches on compatible depth gages\u003c\/li\u003e\n  \u003cli\u003eRod diameter of 5\/32 inch (3.20 mm) for precise fit in 443 and 445 Series gage bodies\u003c\/li\u003e\n  \u003cli\u003eOEM-style replacement rod maintains measurement accuracy of the host instrument\u003c\/li\u003e\n  \u003cli\u003eMaximum measurement capacity of 7.0000 inches (decimal inch)\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit with no minimum order requirement beyond one piece\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 the technician or machinist servicing the depth gage. Before swapping rods, ensure the gage is not under load and the thimble is backed off fully. Handle the rod carefully to avoid nicks or burrs on the rod surface, as surface damage will affect measurement accuracy. Consult the gage manufacturer documentation for proper rod insertion and locking procedures specific to the 443 and 445 Series.\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: 6 to 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement (Decimal Inch)\u003c\/strong\u003e: 7.0000 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: 0.001 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: 71988\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51543031972146,"sku":"71988","price":41.19,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/04d86ea1f2768e362131a0e08d5a69d0.jpg?v=1785914170","url":"https:\/\/voomisupply.com\/products\/starrett-71988-micrometer-rod-6-to-7-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
