It features a 1\/4-20 thread, a 0.125-inch stainless steel ball, and a 0.675-inch body length. The passivated stainless steel body resists corrosion, making this plunger suitable for demanding environments. With an initial end force of 3 pounds and a final end force of 7 pounds, it provides consistent, repeatable detent action. This type of component is typically installed by machinists, tool and die technicians, and mechanical assembly professionals working on fixtures, jigs, or positioning mechanisms.\u003c\/p\u003e\u003cp\u003eThreaded ball plungers like the SSPHB54 are used in light-duty detent and positioning applications across industrial, commercial, and OEM assembly environments. The 1\/4-20 thread allows direct installation into tapped holes in aluminum, steel, or plastic components. With a maximum ball reach of 0.035 inches, this plunger is suited for applications requiring minimal travel with precise, repeatable force engagement. Common use cases include panel alignment, drawer stops, rotary indexing, and component positioning in machine tool fixtures.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 threaded body for direct installation into standard tapped holes\u003c\/li\u003e\n\u003cli\u003e0.125-inch stainless steel ball for durable, low-wear detent contact\u003c\/li\u003e\n\u003cli\u003ePassivated stainless steel body for corrosion resistance in harsh environments\u003c\/li\u003e\n\u003cli\u003eControlled end force: 3 pounds initial, 7 pounds final\u003c\/li\u003e\n\u003cli\u003e0.035-inch maximum ball reach for tight, precise positioning applications\u003c\/li\u003e\n\u003cli\u003eNo locking element  -  allows straightforward installation and adjustment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4-20 threaded ball plunger for use in any tapped hole accepting a 1\/4-20 fastener, suitable for OEM and aftermarket mechanical assembly applications requiring controlled detent force.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a tapped 1\/4-20 hole in the mating component. A licensed machinist or qualified mechanical technician should verify thread engagement depth and torque using appropriate hand tools. De-energize or lock out any associated machinery before servicing or replacing plunger components. Avoid over-torquing the body, as this can restrict ball travel and alter the intended end-force characteristics.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.675 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Ball Reach\u003c\/strong\u003e: 0.035 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 7 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Stainless 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: Passivate\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: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: SSPHB54\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51971345908018,"sku":"SSPHB54","price":17.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76bc33c436af2086f739a62fe3c7c0c2.jpg?v=1789955718","url":"https:\/\/voomisupply.com\/products\/vlier-ssphb54-threaded-ball-plunger-1-4-20-stainless","provider":"Voomi Supply","version":"1.0","type":"link"}
