The plunger features a steel body with a nylon ball and a zinc-plated finish, providing corrosion resistance in light-duty environments. It uses an M12 x 1.75 thread size, making it compatible with standard metric tapped holes. The nylon ball delivers an initial end force of 2.25 pounds and a final end force of 4.5 pounds, allowing consistent, repeatable detent action without damaging mating surfaces. The body measures 0.866 inches in length with a maximum ball reach of 0.098 inches.\u003c\/p\u003e\u003cp\u003eThis ball plunger is suited for use in fixtures, jigs, tooling plates, indexing mechanisms, and light positioning assemblies where a soft, non-marring contact point is required. The nylon ball is appropriate for applications involving softer mating materials or where metal-to-metal contact must be avoided. It is typically installed by machinists, toolmakers, and mechanical assemblers working with precision fixtures or production equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM12 x 1.75 thread for installation into standard metric tapped holes\u003c\/li\u003e\n\u003cli\u003eNylon ball provides non-marring, controlled-force detent action\u003c\/li\u003e\n\u003cli\u003eSteel body with zinc-plated finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eInitial end force of 2.25 pounds and final end force of 4.5 pounds for predictable positioning\u003c\/li\u003e\n\u003cli\u003eMaximum ball reach of 0.098 inches for precise engagement depth\u003c\/li\u003e\n\u003cli\u003eNo locking element  -  allows straightforward installation and removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for installation in metric M12 x 1.75 tapped holes in tooling plates, fixtures, jigs, and indexing assemblies requiring controlled end-force ball plungers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a hex key or appropriate driver into a clean, correctly tapped M12 x 1.75 hole. De-energize or lock out any equipment before servicing assemblies that contain this plunger. Avoid overtightening, as this can restrict ball movement or damage the nylon ball. Confirm ball travel and end-force engagement before returning the assembly to service.\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: No\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: DBML12A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":52078079836466,"sku":"DBML12A","price":20.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/55b5ee238003862644a3089d06b84424_3e22daf3-a71b-4e1e-83a1-4a964d0e39ec.jpg?v=1790053870","url":"https:\/\/voomisupply.com\/products\/vlier-dbml12a-threaded-ball-plunger-m12-x-1-75","provider":"Voomi Supply","version":"1.0","type":"link"}
