It features a zinc-plated steel body and a nylon ball, making it well suited for applications where a softer contact point is needed to avoid marring mating surfaces. The 6-40 thread size allows installation in compact assemblies. Initial end force is 0.5 pounds and final end force is 1 pound, providing a light, consistent spring load. Maximum ball reach is 0.023 inches with a ball diameter of 0.078 inches and a body length of 0.312 inches. Machinists, toolmakers, and mechanical assemblers typically specify this component.\u003c\/p\u003e\n\u003cp\u003eThe DB48 is used in jigs, fixtures, tooling plates, and precision mechanical assemblies where repeatable low-force detenting or part location is required. The nylon ball is appropriate for use against delicate or softer mating surfaces where a steel ball would cause wear or surface damage. The small 6-40 thread profile makes it a practical choice for miniature assemblies and compact mechanisms across light industrial and instrumentation applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-40 thread size for installation in compact and miniature assemblies\u003c\/li\u003e\n  \u003cli\u003eNylon ball contact minimizes surface damage on mating components\u003c\/li\u003e\n  \u003cli\u003eZinc-plated steel body provides corrosion resistance in general-use environments\u003c\/li\u003e\n  \u003cli\u003e0.5 pound initial end force and 1 pound final end force for light, consistent detenting\u003c\/li\u003e\n  \u003cli\u003e0.078 inch ball diameter with 0.023 inch maximum ball reach\u003c\/li\u003e\n  \u003cli\u003ePurple color code for quick field identification during assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use component for mechanical assemblies, jigs, and fixtures requiring a 6-40 threaded ball plunger with a nylon ball contact point.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or mechanical assemblers using standard hand tools appropriate for 6-40 threaded fasteners. Ensure the mating threaded bore is clean and properly tapped to 6-40 specification before installation. Do not overtighten, as excessive torque can damage the small-diameter thread or affect spring preload. Verify ball reach and end force requirements are met for the specific detenting or positioning application before final assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 6-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.078 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Ball Reach\u003c\/strong\u003e: 0.023 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.312 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 1 pound\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\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: DB48\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":52112305783090,"sku":"DB48","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4be7ce29a549855720e005559b7ec5c8_0e06875a-64a5-4c91-8934-2acd2e60a7fc.jpg?v=1790077574","url":"https:\/\/voomisupply.com\/products\/vlier-db48-threaded-ball-plunger-6-40-steel-nylon-ball","provider":"Voomi Supply","version":"1.0","type":"link"}
