It extends the measurement range of the depth gage from 2 to 3 inches, allowing technicians and machinists to take precise depth readings in that range. The rod measures 3.0 inches in overall length with a rod diameter of 1\/8 inch (3.20 mm). At 0.1 pounds, it is a lightweight accessory that integrates directly with compatible depth gage bases. This rod is a direct replacement or supplemental rod for professionals who need to expand their depth gage measurement capability on the job.\u003c\/p\u003e\n\u003cp\u003eThis rod is used in precision measurement applications across machine shops, manufacturing facilities, and field service environments. It is suited for measuring bore depths, slot depths, and step heights in the 2 to 3 inch range. Installers and machinists working in HVAC, plumbing, or industrial trades who require accurate component depth measurements will find this rod a practical addition to the 440 Series depth gage setup. It is sold individually as a single-piece accessory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExtends 440 Series Micrometer Depth Gage measurement range to 2 to 3 inches\u003c\/li\u003e\n  \u003cli\u003eRod diameter of 1\/8 inch (3.20 mm) for precise fitment in depth gage base\u003c\/li\u003e\n  \u003cli\u003eOverall length of 3.0 inches\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.1 pounds for easy handling\u003c\/li\u003e\n  \u003cli\u003eSold individually — one rod per package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the STARRETT 440 Series Micrometer Depth Gages as stated by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this rod should be performed by a qualified machinist or technician familiar with micrometer depth gage assemblies. Ensure the depth gage base is clean and free of debris before seating the rod to maintain measurement accuracy. Do not force the rod into the base — hand-tighten only per the gage manufacturer guidelines. Verify calibration after rod changes before taking critical measurements.\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\u003eMaximum Measurement\u003c\/strong\u003e: 3.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRod Diameter\u003c\/strong\u003e: 1\/8 inch (3.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0 inches\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: 0.1 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: 71975\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51538980438322,"sku":"71975","price":37.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4b62f3bf84914d6a4e5d16dfda8eac8f.jpg?v=1785831655","url":"https:\/\/voomisupply.com\/products\/starrett-71975-micrometer-depth-gage-rod-2-to-3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
