The plunger features a 5\/16-18 unified coarse thread with a 1-inch thread length and a steel body rated for general industrial use. The phenolic nose provides a non-marring contact point, making it suitable for applications where surface protection is a priority. Initial end force is 1.5 pounds, and final end force is 4.5 pounds, delivering a consistent spring-loaded detent action. This part is installed by machinists, maintenance technicians, and mechanical assemblers working on fixtures, jigs, and production equipment.\u003c\/p\u003e\n\u003cp\u003eThe SWPN-5A-G is used in light industrial and manufacturing environments where repeatable positioning or controlled resistance is needed. Typical applications include machine tool fixtures, assembly jigs, sliding mechanisms, and enclosure panels requiring a spring-loaded stop or detent point. The 3\/16-inch plunger projection and 0.135-inch maximum plunger diameter make it well-suited for compact assemblies with limited clearance. The standard plunger length type and 1-inch body length allow straightforward installation into tapped holes without additional hardware.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 unified coarse thread for direct installation into standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eSteel body construction for durability in industrial environments\u003c\/li\u003e\n  \u003cli\u003ePhenolic nose provides non-marring contact with mating surfaces\u003c\/li\u003e\n  \u003cli\u003e1.5-pound initial end force and 4.5-pound final end force for controlled detent action\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch plunger projection with a maximum plunger diameter of 0.135 inches\u003c\/li\u003e\n  \u003cli\u003eNo locking element, allowing straightforward torque-in installation and removal\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 assembly or fixture accepting a 5\/16-18 tapped hole with sufficient depth to accommodate a 1-inch thread length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a properly tapped 5\/16-18 hole and a standard hex wrench or screwdriver slot tool appropriate to the plunger head style. Ensure the mating hole is clean and free of debris before threading in the plunger. Verify plunger projection clearance against mating components before final assembly. Degrease threads if adhesive thread-locking compound is to be applied, as the plunger does not include an integral locking element.\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: None\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: GIBRALTAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SWPN-5A-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51690507272498,"sku":"SWPN-5A-G","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7f39b487e35d05a021c00c7f4e9704a_3872fd5a-dccd-42f8-b84d-c53dae5d8757.jpg?v=1788270745","url":"https:\/\/voomisupply.com\/products\/gibraltar-swpn-5a-g-threaded-spring-plunger-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
