The plunger body is steel with a Delrin nose and a black finish, providing corrosion resistance and reduced friction at the contact point. It features a 1\/4-20 thread with a 1 inch thread length and a plunger projection of 3\/16 inches, with a maximum plunger diameter of 0.119 inches. A built-in locking element prevents the plunger from backing out under vibration, making it suitable for demanding industrial environments. Initial end force is 1 pound and final end force is 4 pounds.\u003c\/p\u003e\u003cp\u003eThis plunger is suited for use in machine tool fixtures, jigs, assembly equipment, and workholding devices where repeatable positioning or light detent action is required. It installs into any tapped 1\/4-20 hole and is appropriate for both production tooling and maintenance applications. The standard-length body and locking element design make it a common choice for OEM equipment builders and tool room technicians working with steel or aluminum fixtures.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 thread with 1 inch thread length for standard tapped-hole installation\u003c\/li\u003e\n\u003cli\u003eLocking element prevents back-out under vibration\u003c\/li\u003e\n\u003cli\u003eDelrin nose reduces friction and protects mating surfaces\u003c\/li\u003e\n\u003cli\u003eSteel body with black finish for durability and corrosion resistance\u003c\/li\u003e\n\u003cli\u003e1 pound initial end force and 4 pound final end force for light-duty indexing\u003c\/li\u003e\n\u003cli\u003e3\/16 inch plunger projection with 0.119 inch maximum plunger diameter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-style replacement or new-install threaded spring plunger for any application requiring a 1\/4-20 tapped hole and a locking-element plunger with standard body length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by threading the plunger into a pre-tapped 1\/4-20 hole using a 1\/8 inch hex key. De-energize or lock out any powered equipment before servicing fixtures or assemblies that contain this component. Do not overtighten, as doing so may damage the locking element or compress the internal spring beyond its operating range. Follow applicable machine safety and tooling standards for your facility.\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\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: 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: 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 30924\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":51972172939570,"sku":"30924","price":15.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/efed977d3e6d68f72ff23efcf2ecb8ed.jpg?v=1789963665","url":"https:\/\/voomisupply.com\/products\/jergens-30924-threaded-spring-plunger-1-4-20-steel-locking","provider":"Voomi Supply","version":"1.0","type":"link"}
