It features a steel body with a stainless steel ball and a zinc-plated finish. The 6-40 thread size, 0.35 inch body length, and 0.078 inch ball diameter make this a compact unit suited for tight tolerance assemblies. Initial end force is 0.5 pounds and final end force is 1 pound, with a maximum ball reach of 0.023 inches. A locking element is incorporated to secure the plunger once installed. Licensed machinists, tool and die technicians, and mechanical assembly professionals typically specify and install this component.\u003c\/p\u003e\n\u003cp\u003eThe PHB48AP is used in applications requiring repeatable, controlled end force  -  such as indexing fixtures, jigs, tooling plates, and light-duty detent mechanisms. Its small thread size and short body length suit it for compact assemblies where space is constrained. The controlled force range makes it appropriate for applications where consistent, predictable ball engagement is required without damaging delicate workpieces or mating surfaces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-40 thread size for compact, precision installations\u003c\/li\u003e\n  \u003cli\u003eStainless steel ball provides corrosion resistance at the contact point\u003c\/li\u003e\n  \u003cli\u003eSteel body with zinc-plated finish for general corrosion protection\u003c\/li\u003e\n  \u003cli\u003eLocking element secures plunger position after adjustment\u003c\/li\u003e\n  \u003cli\u003eControlled end force: 0.5 pounds initial, 1 pound final\u003c\/li\u003e\n  \u003cli\u003ePurple color code for quick field identification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation threaded ball plunger for machinery, fixtures, and tooling assemblies requiring a 6-40 threaded detent or positioning element.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or mechanical assembly technicians using a properly sized driver or hex tool. Ensure the mating threaded hole is clean and free of debris before installation. The locking element should be engaged after the plunger is set to the desired position to prevent backing out under vibration. De-energize or lock out any powered equipment before servicing assemblies that contain this component.\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\u003eBody Length\u003c\/strong\u003e: 0.35 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\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: Stainless Steel\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: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor Code\u003c\/strong\u003e: Purple\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Controlled End Force\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: PHB48AP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51972449632562,"sku":"PHB48AP","price":20.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5fee91fcaa5f10b44e6ef2dc1b2d6ae8_7490e465-1c94-4868-b1be-b2377a9b82b8.jpg?v=1789969211","url":"https:\/\/voomisupply.com\/products\/vlier-phb48ap-threaded-ball-plunger-6-40-steel-body","provider":"Voomi Supply","version":"1.0","type":"link"}
