It features a zinc-plated steel body paired with a stainless steel ball, offering corrosion resistance at the contact point. The 3\/8-16 thread size allows direct installation into standard tapped holes. The ball diameter is 0.188 inches with a maximum ball reach of 0.048 inches. Initial end force is 5 pounds and final end force is 10 pounds, making it suitable for indexing, positioning, and light-duty detent applications. The body length is 0.8 inches. Machinists, tool and die makers, and mechanical assembly technicians are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThe PHB58 is used in light industrial and precision mechanical applications where repeatable positioning or controlled resistance is required. Typical scenarios include jigs, fixtures, tooling plates, and assembly equipment where a spring-loaded ball provides tactile or resistive feedback. The controlled end-force rating makes it appropriate for applications requiring consistent and predictable engagement force without a locking element. It is suited for both OEM equipment builds and field repairs on existing tooling assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 threaded body for installation in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e0.188-inch stainless steel ball for corrosion resistance at the contact surface\u003c\/li\u003e\n  \u003cli\u003e5-pound initial end force and 10-pound final end force for controlled detent action\u003c\/li\u003e\n  \u003cli\u003eZinc-plated steel body for general corrosion protection\u003c\/li\u003e\n  \u003cli\u003e0.8-inch body length fits standard plunger pocket depths\u003c\/li\u003e\n  \u003cli\u003eNo locking element  -  installs and adjusts with standard tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard threaded ball plunger replacement or OEM component for mechanical assemblies, jigs, fixtures, and tooling equipment requiring a 3\/8-16 threaded ball plunger with controlled end-force characteristics.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a tapped 3\/8-16 hole in the mating component. Ensure the assembly is de-energized and secured before installation in any automated or powered fixture. Use a hex key or appropriate driver to thread the plunger to the desired depth, which controls the effective end force at the ball contact point. Do not overtighten, as excessive installation torque can distort the body and affect ball travel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.188 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Ball Reach\u003c\/strong\u003e: 0.048 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 10 pounds\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Controlled End Force\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor Code\u003c\/strong\u003e: Purple\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: PHB58\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":52097177583922,"sku":"PHB58","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/54b1f81d5925f167d5e35620f964663a.jpg?v=1790066755","url":"https:\/\/voomisupply.com\/products\/vlier-phb58-threaded-ball-plunger-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
