The plunger features a 5\/16-18 thread size with a 1 inch thread length and a steel body that provides reliable durability in industrial environments. The phenolic nose resists wear and reduces surface marking on mating components. A locking element is built into the body to prevent the plunger from backing out under vibration or repeated cycling. Initial end force is 1.5 pounds and final end force is 4.5 pounds, making this unit suitable for light-to-moderate retention and detent applications.\u003c\/p\u003e\n\u003cp\u003eThis spring plunger installs into threaded bores in fixtures, jigs, machine frames, and mechanical assemblies where repeatable positioning or light detent action is required. The steel body construction makes it appropriate for general industrial and manufacturing environments. The phenolic plunger nose is suited for applications where contact with softer or finished surfaces is a concern. Installers working on production equipment, tooling, or automation fixtures will find this plunger a straightforward drop-in for standard 5\/16-18 threaded holes. Minimum order quantity is 1 unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 thread size with 1 inch thread length for standard threaded-bore installation\u003c\/li\u003e\n  \u003cli\u003eSteel body construction for durability in industrial service\u003c\/li\u003e\n  \u003cli\u003ePhenolic nose material reduces wear and protects mating surfaces\u003c\/li\u003e\n  \u003cli\u003eBuilt-in locking element prevents back-out under vibration\u003c\/li\u003e\n  \u003cli\u003e1.5 pound initial end force and 4.5 pound final end force for light-to-moderate detent loads\u003c\/li\u003e\n  \u003cli\u003ePlunger diameter range 0.133 to 0.135 inches with 3\/16 inch projection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard threaded spring plunger for use in any application accepting a 5\/16-18 threaded bore where a locking-style plunger with phenolic nose is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a hex key or spanner wrench sized for the body drive feature; thread into a clean, correctly tapped 5\/16-18 hole and torque to the assembler specification for the host material. Ensure the bore is free of chips and debris before threading in the plunger to avoid damage to the locking element. De-energize or lock out any powered equipment before servicing assemblies that contain spring plungers. Do not exceed the rated end force by compressing the plunger nose beyond its specified projection travel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\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: 0.133 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.135 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 1.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 4.5 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  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: GIBRALTAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SWPN-5A-PT-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51693323190578,"sku":"SWPN-5A-PT-G","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7f39b487e35d05a021c00c7f4e9704a_2f80b392-d94d-444e-9e46-8eb07168a47a.jpg?v=1788310620","url":"https:\/\/voomisupply.com\/products\/gibraltar-swpn-5a-pt-g-threaded-spring-plunger-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
