Featuring a 1\/4-20 thread with 1 inch of thread length and a 3\/16 inch plunger projection, this unit delivers an initial end force of 3 pounds, a middle end force of 8 pounds, and a final end force of 13 pounds. The steel body and steel nose offer durability in industrial applications. Machinists, tool and die makers, and mechanical assembly technicians install this type of plunger into tapped holes to index, locate, or retain components through spring-loaded contact.\u003c\/p\u003e\u003cp\u003eThe PH54 is suited for use in fixtures, jigs, machine tool components, and precision mechanical assemblies where a compact, thread-in positioning element is required. The 1\/4-20 thread size is a common standard that fits a wide range of fabricated and machined components. The standard-length plunger body makes it compatible with typical boss depths found in production fixtures and assembly tooling. No locking element is present, making installation and removal straightforward in applications where the plunger must be serviceable or adjustable in the field.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 thread with 1 inch thread length for secure installation in standard tapped holes\u003c\/li\u003e\n\u003cli\u003e3\/16 inch plunger projection with a minimum diameter of 0.117 inches and maximum of 0.118 inches\u003c\/li\u003e\n\u003cli\u003eProgressive force profile: 3 pounds initial, 8 pounds middle, 13 pounds final end force\u003c\/li\u003e\n\u003cli\u003eSteel body and steel nose construction for wear resistance in industrial environments\u003c\/li\u003e\n\u003cli\u003eNo locking element for ease of installation and field serviceability\u003c\/li\u003e\n\u003cli\u003eStandard plunger length type for compatibility with conventional fixture boss depths\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard OEM-style threaded spring plunger for use in machined fixtures, jigs, and mechanical assemblies utilizing 1\/4-20 tapped holes.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by threading the PH54 directly into a properly tapped 1\/4-20 hole using a hex key sized to 0.079 inches across the hex flat. De-energize or lock out any machinery before servicing components in an active assembly. Ensure the mating hole is clean and free of debris before threading the plunger in to avoid damage to the nose or thread. Do not overtighten, as this can restrict plunger travel and reduce effective force output.\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\u003eThread Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Plunger Diameter\u003c\/strong\u003e: 0.117 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.118 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\u003eMiddle End Force\u003c\/strong\u003e: 8 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 13 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.079 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Length Type\u003c\/strong\u003e: Standard\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: PH54\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51972181229874,"sku":"PH54","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7af7520d57dd9d822142dd5d96b47ecf.jpg?v=1789963841","url":"https:\/\/voomisupply.com\/products\/vlier-ph54-threaded-spring-plunger-1-4-20-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
