The plunger features a 1\/4-20 thread with a 1 inch thread length and a standard plunger projection of 3\/16 inches. The nose is made from Delrin, and the body is steel with a black finish. An integrated locking element secures the plunger in place after installation, preventing loosening from vibration. Initial end force is 3 pounds and final end force is 13 pounds, making it well suited for repeatable, low-force detent applications.\u003c\/p\u003e\n\u003cp\u003eThis spring plunger is used in jigs, fixtures, tooling plates, machine housings, and other precision assemblies where controlled positioning or light retention is required. The 1\/4-20 thread is a common inch-series size that installs directly into tapped holes in steel, aluminum, and other standard tooling materials. The locking element eliminates the need for thread-locking compounds in most applications. Typical installers include tool and die technicians, machine builders, and maintenance mechanics working on production equipment or custom fixtures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 thread with 1 inch thread length for standard tapped-hole installation\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch plunger projection provides consistent detent engagement depth\u003c\/li\u003e\n  \u003cli\u003eDelrin nose reduces wear on mating surfaces during repeated cycling\u003c\/li\u003e\n  \u003cli\u003eSteel body with black finish for corrosion resistance in typical shop environments\u003c\/li\u003e\n  \u003cli\u003eIntegrated locking element prevents back-out under vibration without thread locker\u003c\/li\u003e\n  \u003cli\u003e3 pound initial end force and 13 pound final end force for controlled, repeatable positioning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install threaded spring plunger for jigs, fixtures, and mechanical assemblies using standard 1\/4-20 tapped holes.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a tapped 1\/4-20 hole to the appropriate depth. Use a 1\/8 inch hex key to drive the plunger to the desired installation depth. Power down or de-energize any associated equipment before servicing assemblies containing this plunger. Avoid over-torquing, which can damage the locking element or distort the thread form.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003ePlunger Projection\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.119 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: 13 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: Delrin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 1\/8 inch\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\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: JERGENS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 30524\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":52041212231986,"sku":"30524","price":15.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/61b0c039ae910a13b813c26ff48e0923.jpg?v=1790027590","url":"https:\/\/voomisupply.com\/products\/jergens-30524-threaded-spring-plunger-1-4-20-steel-locking","provider":"Voomi Supply","version":"1.0","type":"link"}
