The body is machined from steel with a 1\/4-28 unified fine thread and measures 1 inch in both body length and thread length. The plunger tip is nylon, with a minimum diameter of 0.116 inches and a maximum diameter of 0.118 inches, and delivers a 3\/16 inch projection. Initial end force is 1 pound and final end force is 4 pounds. A built-in locking element secures the plunger position once installed, preventing vibration-induced back-out during service.\u003c\/p\u003e\u003cp\u003eThis spring plunger suits precision-fit applications in jigs, fixtures, tooling, and machine components where repeatable detent positioning is required. The 1\/4-28 fine thread allows for controlled torque installation into threaded bores in steel, aluminum, or engineered plastic housings. The nylon nose protects mating surfaces from scoring or galling, making this part appropriate for use in sliding-contact or intermittent-engagement assemblies. Machinists, toolmakers, and maintenance technicians working in industrial, manufacturing, and OEM equipment environments are the typical end users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSteel body construction for strength and durability in mechanical assemblies\u003c\/li\u003e\n\u003cli\u003eNylon plunger nose protects mating surfaces from damage during contact\u003c\/li\u003e\n\u003cli\u003eLocking element prevents vibration-induced loosening after installation\u003c\/li\u003e\n\u003cli\u003e1\/4-28 unified fine thread for precise, controlled engagement\u003c\/li\u003e\n\u003cli\u003e3\/16 inch plunger projection with 1 pound initial and 4 pound final end force\u003c\/li\u003e\n\u003cli\u003eStandard plunger length type for straightforward drop-in replacement or new installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation spring plunger for threaded bores requiring a 1\/4-28 fine-thread fit in jigs, fixtures, tooling, and mechanical assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a properly tapped 1\/4-28 threaded bore in the host component. Use an appropriate hex key or spanner tool per the plunger head style to thread the body in by hand, then torque to the host material specification. Power down or de-energize any associated equipment before servicing assemblies containing spring plungers. Do not over-drive the plunger, as bottoming out can damage the internal spring or locking element.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28\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: Nylon\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: SWN10-4Y-PT-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51691240358194,"sku":"SWN10-4Y-PT-G","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7f39b487e35d05a021c00c7f4e9704a_efdddb78-fed1-4a53-a1b2-24d3b63fde80.jpg?v=1788281999","url":"https:\/\/voomisupply.com\/products\/gibraltar-swn10-4y-pt-g-threaded-spring-plunger-1-4-28","provider":"Voomi Supply","version":"1.0","type":"link"}
