The steel body houses a nylon ball that extends and retracts under controlled force, providing consistent detent action without metal-on-metal contact at the ball interface. With an initial end force of 8 pounds and a final end force of 18 pounds, this plunger suits applications where controlled resistance and positive location are required. The flanged body allows flush, interference-fit installation into a bored hole without threads or adhesives. Machinists, toolmakers, and mechanical assembly technicians install this type of component in jigs, fixtures, and production tooling.\u003c\/p\u003e\n\u003cp\u003eThe DPFB60 is suited for use in industrial fixtures, automation tooling, machine frames, and precision jigs where repeatable part location is needed. The flanged design seats against a counterbored surface to resist axial pullout under load. The nylon ball protects mating surfaces from galling or scoring, making it appropriate for use against softer substrates such as aluminum or plastic workpieces. It is installed in a single-pass press or arbor press operation into a prepared bore.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSteel body with black finish for corrosion resistance and identification\u003c\/li\u003e\n  \u003cli\u003eNylon ball reduces surface damage to mating or indexed components\u003c\/li\u003e\n  \u003cli\u003ePress fit installation requires no threads, adhesives, or special tooling beyond a standard arbor press\u003c\/li\u003e\n  \u003cli\u003eIntegrated flange seats against counterbore to resist axial displacement under load\u003c\/li\u003e\n  \u003cli\u003e8 pound initial force and 18 pound final force for controlled, positive detent engagement\u003c\/li\u003e\n  \u003cli\u003eCompact 0.5 inch body diameter fits standard bored pocket configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a press fit replacement or new-installation ball plunger for industrial jigs, fixtures, and mechanical assemblies requiring flanged, non-threaded detent hardware with a 0.5 inch body diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinist or toolroom personnel using an arbor press or hydraulic press into a precision-bored hole sized to the required interference fit tolerance. Ensure the bore depth and counterbore dimensions match the body length and flange geometry before pressing. Do not hammer directly on the nylon ball. Verify bore alignment before pressing to prevent body damage or misalignment of the ball axis.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.438 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Ball Reach\u003c\/strong\u003e: 0.161 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Diameter\u003c\/strong\u003e: 0.688 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Thickness\u003c\/strong\u003e: 0.11 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Flange\u003c\/strong\u003e: 1.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 8 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 18 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: +0.002 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\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: DPFB60\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":52065128808754,"sku":"DPFB60","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4c5fc708bed019e928a212b6bdd59ca8_4e86af71-2adf-4818-b730-9102889a7f4c.jpg?v=1790044585","url":"https:\/\/voomisupply.com\/products\/vlier-dpfb60-steel-press-fit-ball-plunger-0-5in","provider":"Voomi Supply","version":"1.0","type":"link"}
