It features a 1\/4-20 thread and a 5\/8-inch thread length, making it straightforward to install in pre-tapped housings. The plunger nose and body are both steel construction with a black finish. Initial end force is 0.3 pounds and final end force is 3.5 pounds, giving the plunger a firm seat when fully engaged. The 3\/16-inch projection keeps the nose profile low. Machinists, tool-and-die makers, and assembly technicians working on jigs, fixtures, and indexing mechanisms are the primary installers of this type of hardware.\u003c\/p\u003e\n\u003cp\u003eThis spring plunger is suited for use in machine tool fixtures, assembly jigs, stamping dies, and general industrial positioning applications where repeatable detent action is needed. The short body length of 5\/8 inch fits installations with limited axial depth. The 0.119-inch maximum plunger diameter accommodates tight-clearance bores. No locking element is present, so the plunger threads directly into a tapped bore without a secondary jam-nut feature. Typical applications include panel alignment pins, drawer indexing, and light-duty retaining functions in both OEM equipment and custom tooling builds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 thread size with 5\/8-inch thread length for standard tapped-hole installation\u003c\/li\u003e\n  \u003cli\u003eShort body profile at 5\/8 inch suits depth-restricted mounting bores\u003c\/li\u003e\n  \u003cli\u003e0.3-pound initial end force and 3.5-pound final end force for positive detent engagement\u003c\/li\u003e\n  \u003cli\u003eSteel body and steel nose with black finish for durability in industrial environments\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch plunger projection maintains a low nose extension when engaged\u003c\/li\u003e\n  \u003cli\u003eNo locking element  -  simple threaded installation into a pre-tapped hole\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct installation component for machine fixtures, assembly jigs, and industrial tooling assemblies requiring a short-body 1\/4-20 threaded spring plunger with steel construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or assembly technicians using a standard hex key or screwdriver slot appropriate to the plunger head style. Thread the plunger into a clean, properly tapped 1\/4-20 hole, ensuring the bore depth accommodates the full body length before torquing to the fixture specification. De-energize or lock out any machinery before servicing fixtures or jigs that contain this plunger. Do not overtighten  -  steel threads in softer housing materials can strip if excessive force is applied.\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: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 5\/8 inches\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: 0.3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 3.5 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\u003ePlunger Length Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\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: 27004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":51962423836978,"sku":"27004","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9e885478a53123404be0d12fc409aed1.jpg?v=1789947678","url":"https:\/\/voomisupply.com\/products\/jergens-27004-threaded-spring-plunger-1-4-20-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
