The rod allows depth measurements from 3 to 4 inches, making it a direct accessory for field calibration work and precision machining applications. With a rod diameter of 4.00 mm and an overall length of 180.50 mm, this rod meets the dimensional tolerances required for accurate depth readings. It is installed by machinists, tool and die technicians, and metrology professionals who service or operate Mitutoyo depth micrometer sets.\u003c\/p\u003e\u003cp\u003eThis rod is used in manufacturing, machine shops, and inspection environments where precise depth measurements are required. It is suited for both production floor use and quality control inspection stations. The 983508 extends the usable range of a depth micrometer set, allowing a single base unit to cover multiple measurement intervals by swapping rods as needed. Sold individually, it covers the 3 to 4 inch measurement interval.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCovers the 3 to 4 inch depth measurement range\u003c\/li\u003e\n\u003cli\u003eRod diameter of 4.00 mm for compatibility with Mitutoyo depth micrometer bases\u003c\/li\u003e\n\u003cli\u003eOverall length of 180.50 mm\u003c\/li\u003e\n\u003cli\u003eSold as a single replacement rod\u003c\/li\u003e\n\u003cli\u003eAccessory type: rod, for use as a direct swap in compatible depth mic sets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 129 and 329 series Mitutoyo depth micrometers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eRod replacement on a depth micrometer should be performed by a qualified machinist or metrologist on a clean, stable work surface. Ensure the micrometer base is fully cleared of debris before inserting the rod to avoid damage to the measuring faces. Follow the instrument manufacturer's service instructions for proper rod seating and zero verification after installation. Recalibrate the instrument against a known reference standard after any rod change.\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\u003eMeasurement Range\u003c\/strong\u003e: 3 to 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 4.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRod Diameter\u003c\/strong\u003e: 4.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 180.50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.85 pounds\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: MITUTOYO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 983508\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51557709316402,"sku":"983508","price":30.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e10b4bcca5648fbe31688b35c9775074.jpg?v=1786393303","url":"https:\/\/voomisupply.com\/products\/mitutoyo-983508-depth-micrometer-rod-3-to-4-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
