It features a stainless steel body with an M8 x 1.25 thread and a nylon ball measuring 0.196 inches in diameter. The body length is 0.63 inches with a maximum ball reach of 0.059 inches. Initial end force is rated at 9 pounds and final end force at 13.49 pounds, providing consistent, repeatable positioning force. This plunger is installed by machinists, maintenance technicians, and mechanical assemblers in jigs, fixtures, and precision tooling where controlled detent force is required.\u003c\/p\u003e\u003cp\u003eThe DSBMH8 is suited for light-duty controlled-force positioning tasks in manufacturing and assembly environments. Its nylon ball minimizes surface marring on workpieces and mating components, making it appropriate for use in fixture bodies, tooling plates, and positioning systems where metal-on-metal contact is undesirable. The M8 x 1.25 thread is a standard metric size found across a wide range of machined components and assemblies. The purple color code identifies the specific force rating within the VLIER product line for quick visual identification during installation and maintenance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM8 x 1.25 thread pitch for standard metric fitment\u003c\/li\u003e\n\u003cli\u003eStainless steel body for corrosion resistance in shop and industrial environments\u003c\/li\u003e\n\u003cli\u003eNylon ball reduces surface marring on mating components\u003c\/li\u003e\n\u003cli\u003eControlled end force: 9 pounds initial, 13.49 pounds final\u003c\/li\u003e\n\u003cli\u003eCompact body length of 0.63 inches suits space-constrained assemblies\u003c\/li\u003e\n\u003cli\u003ePurple color code for quick force-rating identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-install threaded ball plunger for M8 x 1.25 tapped holes in jigs, fixtures, tooling plates, and mechanical assemblies requiring controlled detent or positioning force.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or mechanical assemblers using a standard hex wrench or spanner suited to the M8 body. Always ensure the mating tapped hole is clean and correctly threaded before installation. Do not overtighten the body, as this can affect ball travel and end-force performance. No special codes govern installation of mechanical plungers, but follow the equipment manufacturer's torque and assembly guidelines for the host 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\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: 9 pounds (40.03 N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 13.49 pounds (60.00 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\u003eApplication\u003c\/strong\u003e: Controlled End Force\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Code\u003c\/strong\u003e: Purple\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\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: DSBMH8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51972007493938,"sku":"DSBMH8","price":15.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cdfa3da703e86fcb203ef79a98b3036d.jpg?v=1789960736","url":"https:\/\/voomisupply.com\/products\/vlier-dsbmh8-threaded-ball-plunger-m8-x-1-25","provider":"Voomi Supply","version":"1.0","type":"link"}
