The plunger threads into a tapped hole using a 5\/16-18 thread and delivers controlled end force through a spring-loaded steel nose. Initial end force is 3 pounds and final end force reaches 15 pounds, making it suitable for light-to-medium positioning and detent applications. The steel body and steel nose provide durability in industrial and machine-tool environments. Machinists, toolmakers, and mechanical assemblers install this type of component in fixtures, jigs, and production equipment.\u003c\/p\u003e\n\u003cp\u003eThis plunger is used in precision fixturing, workholding, and assembly tooling where repeatable positioning or spring-loaded retention is required. Its 1 inch thread length allows full engagement in standard-depth tapped holes. The 3\/16 inch plunger projection provides the working stroke needed for most indexing and detent setups. No locking element is present, so the plunger can be threaded in and adjusted to depth using a 3\/32 inch hex wrench before final positioning in the host component.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 thread for direct installation into standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e3 pounds initial end force and 15 pounds final end force for reliable detent and positioning action\u003c\/li\u003e\n  \u003cli\u003eSteel body and steel nose for durability in industrial tooling environments\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch plunger projection provides consistent working stroke\u003c\/li\u003e\n  \u003cli\u003eAdjustable install depth via 3\/32 inch hex drive  -  no locking element\u003c\/li\u003e\n  \u003cli\u003eStandard plunger length type for common fixturing and jig applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install component for mechanical fixtures, jigs, workholding devices, and production tooling that accept a 5\/16-18 threaded spring plunger with a 1 inch thread length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or mechanical assemblers using a 3\/32 inch hex wrench. Thread the plunger into the pre-tapped 5\/16-18 hole and adjust to the desired depth before the assembly is placed in service. Ensure the mating hole is clean and free of chips or debris before threading in the plunger. Do not overtighten, as the body has no locking element and relies on thread friction or adhesive if permanent positioning is required.\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\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.135 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\u003eFinal End Force\u003c\/strong\u003e: 15 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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 3\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.15 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: 57008XG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":67581988340018,"sku":"57008XG","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cc36f86d8b5afb15af12854362a9ea68.jpg?v=1790411333","url":"https:\/\/voomisupply.com\/products\/gibraltar-57008xg-threaded-spring-plunger-5-16-18-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
