The plunger features a zinc-plated steel body with an M8 x 1.25 thread and a nylon ball that delivers a smooth, consistent detent or positioning action. Initial end force is 1.12 pounds and final end force is 2.25 pounds, making this part suitable for light-duty indexing and positioning tasks where repeatable, controlled resistance is required. The locking element prevents the plunger from backing out under vibration. Machinists, tool and die makers, and mechanical assembly technicians are the primary installers of this component.\u003c\/p\u003e\u003cp\u003eThis ball plunger is used in fixtures, jigs, machine tooling, and mechanical assemblies where a nylon ball contact surface is preferred to avoid marring or scratching the mating component. The M8 x 1.25 threaded body allows installation into standard metric tapped holes. The nylon ball and zinc-plated steel construction make it appropriate for general industrial and light mechanical environments. The integrated locking element suits installations where vibration could otherwise cause the plunger to loosen over time.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM8 x 1.25 threaded body for installation into standard metric tapped holes\u003c\/li\u003e\n\u003cli\u003eNylon ball provides non-marring contact on mating surfaces\u003c\/li\u003e\n\u003cli\u003eZinc-plated steel body for corrosion resistance in general industrial use\u003c\/li\u003e\n\u003cli\u003eIntegrated locking element prevents back-out under vibration\u003c\/li\u003e\n\u003cli\u003e1.12 lb initial end force and 2.25 lb final end force for controlled detent action\u003c\/li\u003e\n\u003cli\u003ePurple color code for quick identification during assembly and maintenance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for controlled end-force detent and positioning applications in fixtures, jigs, and mechanical assemblies that accept an M8 x 1.25 threaded ball plunger.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using standard metric hex tools into a properly tapped M8 x 1.25 through or blind hole. Ensure the mating surface is clean and the hole is deburred before threading in the plunger. The locking element should be engaged to the manufacturer's specified seating depth to secure the plunger against loosening. De-energize and lock out any powered equipment before servicing assemblies that contain this component.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M8 x 1.25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 1.25 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.196 inches (5.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.63 inches (16.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Ball Reach\u003c\/strong\u003e: 0.059 inches (1.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 1.12 lb (5.00 N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 2.25 lb (10.00 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: DBML8AN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51972414046514,"sku":"DBML8AN","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5d41b1381173934a646473fd5fad82ae.jpg?v=1789968016","url":"https:\/\/voomisupply.com\/products\/vlier-dbml8an-threaded-ball-plunger-m8-x-1-25-steel-nylon","provider":"Voomi Supply","version":"1.0","type":"link"}
