It features a stainless steel body with an M8 x 1.25 thread and a nylon ball that provides smooth, repeatable engagement without marring mating surfaces. The ball diameter measures 0.196 inches (5.00 mm), the body length is 0.63 inches, and the maximum ball reach is 0.059 inches (1.50 mm). Initial end force is 3.37 pounds and final end force is 6.75 pounds, making this plunger suitable for moderate-load positioning tasks. It is installed by machinists, tool and die makers, and mechanical assembly technicians.\u003c\/p\u003e\u003cp\u003eThis ball plunger is used in jigs, fixtures, tooling plates, and machine assemblies where repeatable part positioning or light detent feedback is required. The nylon ball is appropriate for applications where a softer contact material is needed to protect sensitive surfaces or reduce noise during engagement. The M8 x 1.25 thread allows direct installation into tapped bores in steel, aluminum, or plastic assemblies without additional hardware.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eStainless steel body resists corrosion in wash-down or high-humidity environments\u003c\/li\u003e\n\u003cli\u003eNylon ball provides non-marring contact for delicate or finished mating surfaces\u003c\/li\u003e\n\u003cli\u003eM8 x 1.25 thread for direct installation into standard tapped bores\u003c\/li\u003e\n\u003cli\u003e3.37 lb initial end force and 6.75 lb final end force for consistent detent performance\u003c\/li\u003e\n\u003cli\u003eMaximum ball reach of 0.059 inches (1.50 mm) suits tight-tolerance positioning applications\u003c\/li\u003e\n\u003cli\u003eColor code: Purple for quick field identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard threaded ball plunger for use in any application requiring an M8 x 1.25 tapped bore for indexing, positioning, or detent functions in mechanical assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by threading the body directly into a pre-tapped M8 x 1.25 bore using a hex key or appropriate driver on the body flats. Ensure the mating bore is clean and free of debris before installation to avoid damaging the nylon ball or thread. Do not overtighten, as excessive torque can deform the nylon ball or strip the threaded body. Follow applicable machine safety lockout and tagout procedures before servicing any assembly containing 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\u003eBody Length\u003c\/strong\u003e: 0.63 inches\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\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: 3.37 pounds (15.00 N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 6.75 pounds (30.03 N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Material\u003c\/strong\u003e: Nylon\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: DSBM8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":52042270474546,"sku":"DSBM8","price":16.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/54c5fc78f66017069bfbf62fb53f96e2.jpg?v=1790028261","url":"https:\/\/voomisupply.com\/products\/vlier-dsbm8-threaded-ball-plunger-m8-x-1-25","provider":"Voomi Supply","version":"1.0","type":"link"}
