It features a 1\/4-20 thread size with a 1 inch thread length and a standard-length steel body measuring 1 inch. The phenolic nose provides a non-marring contact point, while the integrated locking element secures the plunger in position once installed. Initial end force is 1 pound and final end force is 4 pounds, making this plunger suitable for light-load positioning tasks. Licensed tradespeople and machine assemblers install this type of component in fixtures, jigs, enclosures, and production tooling.\u003c\/p\u003e\u003cp\u003eThis spring plunger is used in both light industrial and OEM assembly applications where a repeatable, spring-loaded detent or positioning point is required. Typical installations include machine frames, tool fixtures, enclosures, and adjustable mechanical assemblies where the plunger nose engages a drilled hole or groove to hold a component in a set position. The locking element prevents the plunger from backing out under vibration, making it suitable for dynamic or high-cycle environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 thread size with 1 inch thread length for direct installation into tapped holes\u003c\/li\u003e\n\u003cli\u003eSteel body construction for durability in industrial environments\u003c\/li\u003e\n\u003cli\u003ePhenolic nose material provides non-marring contact at the plunger tip\u003c\/li\u003e\n\u003cli\u003eIntegrated locking element prevents plunger from loosening under vibration\u003c\/li\u003e\n\u003cli\u003e1 pound initial end force and 4 pound final end force for light-load positioning\u003c\/li\u003e\n\u003cli\u003eStandard plunger length type for common fitment in tooling and fixture applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard threaded spring plunger for use in any application requiring a 1\/4-20 tapped hole and a spring-loaded positioning or detent function.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a hex key or appropriate driver into a clean, properly tapped 1\/4-20 through or blind hole. Ensure the mating surface is free of debris before threading in the plunger to avoid cross-threading. The locking element should be engaged fully to resist back-out during service. Always follow the equipment manufacturer's assembly specifications when installing spring plungers in load-bearing or safety-critical fixtures.\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: 0.116 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: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 4 pounds\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: Phenolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Length Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: GIBRALTAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SWPN-4A-PT-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51689314091314,"sku":"SWPN-4A-PT-G","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d7bca26e3627446bc96592d53120bb5c.jpg?v=1788257382","url":"https:\/\/voomisupply.com\/products\/gibraltar-swpn-4a-pt-g-threaded-spring-plunger-1-4-20","provider":"Voomi Supply","version":"1.0","type":"link"}
