It extends the measurement range of the base gage, allowing depth measurements up to 5.0 inches. The rod features a standard anvil-type end and is built to maintain the precision tolerances required for micrometer-grade measurement work. Machinists, tool-and-die technicians, and quality control personnel install this rod when expanding or replacing the rod set on a 449 Series depth gage. Accurate depth measurement depends on rod condition, so damaged or worn rods should be replaced rather than reused.\u003c\/p\u003e\u003cp\u003eThis rod is intended for shop floor and inspection environments where the 449 Series Micrometer Depth Gage is already in service. It suits applications that require incremental range extension on a depth gage, such as measuring stepped bores, blind holes, or recessed features. The rod is sold individually and fits the standard 449 Series base without modification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExtends depth gage range up to 5.0 inches maximum measurement\u003c\/li\u003e\n\u003cli\u003eRod-type anvil end for consistent contact on flat surfaces\u003c\/li\u003e\n\u003cli\u003eDirect replacement for 449 Series Micrometer Depth Gage accessories\u003c\/li\u003e\n\u003cli\u003eSold as a single rod — order quantity of one unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with STARRETT 449 Series Micrometer Depth Gages as a direct accessory rod replacement.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or metrology technicians familiar with micrometer depth gage accessories. Before swapping rods, ensure the gage is clean and free of chips or debris at the rod seat. Handle the rod by its body to avoid contact with the measuring surfaces. Verify zero calibration after installing any new rod before taking measurements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccessory Type\u003c\/strong\u003e: Rod\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnvil Type\u003c\/strong\u003e: Rod\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 5.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: 449 Series Micrometer Depth Gages\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 71842\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542253470002,"sku":"71842","price":47.23,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd9b817fe4de33821d40e3fe53195030.jpg?v=1785896466","url":"https:\/\/voomisupply.com\/products\/starrett-71842-micrometer-rod-449-series-depth-gages","provider":"Voomi Supply","version":"1.0","type":"link"}
