The body is steel with a zinc-plated finish, and the ball is nylon, making the combination well suited for indexing, positioning, and detent functions where a softer ball contact is required. Thread size is M12 x 1.75. The body measures 0.866 inches in length, the ball diameter is 0.315 inches, and maximum ball reach is 0.098 inches. Initial end force is 2.25 pounds and final end force is 4.5 pounds. A locking element is included to secure the plunger in the threaded bore after installation.\u003c\/p\u003e\u003cp\u003eThis ball plunger is used in machine tool fixtures, jigs, automation equipment, and precision positioning assemblies where repeatable detent or indexing force is needed. The nylon ball minimizes surface marking on mating components. The zinc-plated steel body resists light corrosion in typical shop environments. It is identified by a purple color code for quick force-range identification in multi-plunger installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM12 x 1.75 thread for direct installation into standard tapped bores\u003c\/li\u003e\n\u003cli\u003eSteel body with zinc-plated finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eNylon ball reduces marking and wear on mating surfaces\u003c\/li\u003e\n\u003cli\u003eLocking element secures plunger position after torquing\u003c\/li\u003e\n\u003cli\u003eControlled end force: 2.25 pounds initial, 4.5 pounds final\u003c\/li\u003e\n\u003cli\u003ePurple color code for fast force-range identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for installation in any application requiring an M12 x 1.75 threaded ball plunger with controlled end-force characteristics and a locking element.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by threading the plunger into a tapped M12 x 1.75 bore using a hex key or spanner appropriate for the body style. Ensure the bore thread is clean and free of debris before installation. The locking element should be engaged after the plunger is set to the desired position to prevent back-out during service. No special certifications are required for this mechanical fastener, but follow any applicable equipment manufacturer torque guidelines for the host assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M12 x 1.75\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 1.75 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.315 inches (8.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.866 inches (22.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Ball Reach\u003c\/strong\u003e: 0.098 inches (2.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 2.25 pounds (10.00 N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 4.50 pounds (20.00 N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Material\u003c\/strong\u003e: Nylon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Code\u003c\/strong\u003e: Purple\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VLIER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: DBML12AN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":52124264628530,"sku":"DBML12AN","price":20.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aedb8b68cdea952ad682ba1958207d00.jpg?v=1790086684","url":"https:\/\/voomisupply.com\/products\/vlier-dbml12an-threaded-ball-plunger-m12-x-1-75","provider":"Voomi Supply","version":"1.0","type":"link"}
