It features a zinc-plated steel body with an M12 x 1.75 thread and a nylon ball measuring 0.315 inches in diameter. The nylon ball provides smooth, low-friction contact with mating surfaces while protecting softer workpiece materials from marring. With an initial end force of 16.86 pounds and a final end force of 25.85 pounds, this plunger delivers consistent spring-loaded engagement suited to production tooling, fixtures, and machine components. Mechanical assemblers, toolmakers, and maintenance technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis ball plunger is used in industrial and manufacturing settings where repeatable positioning or detent action is needed. Typical applications include fixture plates, jigs, sliding components, and panel assemblies where a spring-loaded nylon ball must engage a mating detent hole or groove. The M12 x 1.75 thread suits metric-tapped housings common in European and metric-standard equipment. The 0.866 inch body length and 0.098 inch maximum ball reach are appropriate for shallow-thread installations where envelope space is limited.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM12 x 1.75 threaded body for direct installation into metric-tapped bores\u003c\/li\u003e\n  \u003cli\u003eNylon ball resists marring on soft or coated mating surfaces\u003c\/li\u003e\n  \u003cli\u003eZinc-plated steel body provides corrosion resistance in general industrial environments\u003c\/li\u003e\n  \u003cli\u003e16.86 pound initial end force and 25.85 pound final end force for consistent detent engagement\u003c\/li\u003e\n  \u003cli\u003e0.098 inch maximum ball reach suits shallow-clearance detent applications\u003c\/li\u003e\n  \u003cli\u003ePurple color code for quick field identification of force and size specification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation ball plunger for metric-tapped housings requiring an M12 x 1.75 threaded plunger with a nylon ball and steel body.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by mechanical assemblers or toolmakers using a hex wrench or open-end wrench sized for the body flats. De-energize or lock out any machine before servicing components in moving assemblies. Thread the plunger into a clean, properly tapped M12 x 1.75 bore and tighten to a snug fit without over-torquing the threaded body. Verify ball engagement depth against the mating detent geometry before returning the assembly to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M12 x 1.75\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.866 inches\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\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: 16.86 pounds (75.00 N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 25.85 pounds (115.00 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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: DBMH12A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51972952555826,"sku":"DBMH12A","price":17.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bcf37fd8119921b043eb0b0bddff85db.jpg?v=1789971365","url":"https:\/\/voomisupply.com\/products\/vlier-dbmh12a-threaded-ball-plunger-m12-x-1-75","provider":"Voomi Supply","version":"1.0","type":"link"}
