It features a 1\/4-20 thread size with a 1 inch thread length and a steel body and nose for durability in industrial and trade service environments. The plunger delivers 1 pound of initial end force and 4 pounds of final end force, making it suitable for consistent, repeatable positioning under moderate spring load. This plunger ships individually and is installed by machinists, maintenance technicians, and assembly professionals working with jigs, fixtures, and mechanical positioning components.\u003c\/p\u003e\u003cp\u003eThis spring plunger is used in light mechanical assemblies where a retractable, spring-loaded nose is needed to hold or index a component in place. Typical applications include machine tool fixtures, panel assemblies, and precision positioning jigs in both production and maintenance settings. The 3\/16 inch plunger projection provides adequate travel for standard indexing tasks. The absence of a locking element means the plunger threads freely into the receiving hole without staking or adhesive required for standard service conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 thread size with 1 inch thread length for standard tapped-hole installation\u003c\/li\u003e\n\u003cli\u003eMaximum plunger diameter of 0.118 inches with 3\/16 inch projection\u003c\/li\u003e\n\u003cli\u003e1 pound initial end force and 4 pound final end force for consistent spring-loaded indexing\u003c\/li\u003e\n\u003cli\u003eSteel body and nose construction for durability in industrial environments\u003c\/li\u003e\n\u003cli\u003eNo locking element  -  installs and removes without staking or thread-locking treatment\u003c\/li\u003e\n\u003cli\u003eStandard plunger length type suitable for common fixture and jig applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-install threaded spring plunger for mechanical assemblies, jigs, and fixtures that accept a 1\/4-20 threaded hole with standard plunger geometry.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by threading the plunger body into a tapped 1\/4-20 hole using a hex key or appropriate drive tool. Ensure the receiving hole is clean and free of debris before installation. No power source is required, but always de-energize or lock out any machine or assembly before servicing spring plunger positions. Do not over-torque the plunger body, as the steel threads can seize or strip in softer substrate materials.\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\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.118 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 3\/16 inch (0.1875 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: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: None\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: 0.15 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: SW10-4A-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":67914936123698,"sku":"SW10-4A-G","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/46e6e864cd1e5fcf247880961c6342f3.jpg?v=1791251608","url":"https:\/\/voomisupply.com\/products\/gibraltar-sw10-4a-g-threaded-spring-plunger-1-4-20","provider":"Voomi Supply","version":"1.0","type":"link"}
