The body is steel with a zinc-plated finish, and the ball is nylon, offering smooth, low-friction contact against mating surfaces. The M8 x 1.25 thread allows direct installation into tapped holes without additional hardware. Key performance values are 9 pounds initial end force and 13.49 pounds final end force, making this plunger suitable for consistent, repeatable positioning under moderate load. Licensed mechanical technicians and assembly professionals typically install this component during machine builds or fixture setups.\u003c\/p\u003e\u003cp\u003eThis ball plunger is used in industrial machinery, jigs, fixtures, and positioning assemblies where a spring-loaded nylon ball provides controlled detent or alignment feedback. The nylon ball material is well suited for applications requiring gentle contact with soft or coated surfaces, minimizing marking or damage to the mating part. Its compact body length of 0.63 inches makes it appropriate for space-constrained installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM8 x 1.25 thread for direct installation into standard tapped holes\u003c\/li\u003e\n\u003cli\u003eSteel body with zinc-plated finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eNylon ball for low-friction, non-marring contact\u003c\/li\u003e\n\u003cli\u003e9 pounds initial end force and 13.49 pounds final end force for consistent detent action\u003c\/li\u003e\n\u003cli\u003eMaximum ball reach of 0.059 inches\u003c\/li\u003e\n\u003cli\u003eCompact body length of 0.63 inches suits tight installation clearances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style threaded ball plunger for use in industrial fixtures, jigs, and positioning assemblies requiring an M8 x 1.25 threaded plunger with a nylon ball.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by mechanical assemblers or maintenance technicians using standard hand tools. Thread the plunger into a pre-tapped M8 x 1.25 hole and torque to the assembly specification for the host material. Ensure the mating surface is clean and free of debris before seating the plunger to avoid damage to the nylon ball. De-energize or lock out any associated machinery before servicing or replacing plungers in active assemblies.\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: 9.00 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: 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: DBMH8A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":52109383860530,"sku":"DBMH8A","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68dc382a76a54fa49253af51ce3e308b.jpg?v=1790075560","url":"https:\/\/voomisupply.com\/products\/vlier-dbmh8a-threaded-ball-plunger-m8-x-1-25","provider":"Voomi Supply","version":"1.0","type":"link"}
