The steel construction delivers durability in demanding environments. End force ranges from 1.25 pounds initial to 5 pounds final, providing controlled resistance appropriate for repeatable positioning tasks. The 0.38-inch diameter plunger extends 0.44 inches of projection, and the overall body length is 1 inch. Installers working with jigs, fixtures, tool holders, or mechanical subassemblies will find this plunger a direct fit for standard threaded mounting holes.\u003c\/p\u003e\n\u003cp\u003eThe PRSN625 suits light industrial and mechanical assembly applications where a manually retractable, non-locking plunger is required. The pull ring design allows the operator to retract the plunger by hand without tools, making it well-suited for production fixtures, assembly jigs, positioning stops, and panel hardware where frequent operator interaction is expected. The 5\/8-11 thread size is compatible with standard tapped holes in steel, aluminum, and fabricated frames commonly found in manufacturing and machine-tool environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNon-locking pull ring design allows tool-free manual retraction\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 thread for direct installation into standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e1.25 pound initial to 5 pound final end force for controlled positioning resistance\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in industrial environments\u003c\/li\u003e\n  \u003cli\u003e0.44-inch plunger projection with 0.38-inch plunger diameter\u003c\/li\u003e\n  \u003cli\u003e0.62-inch hex for wrench-assisted installation and torque control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install spring plunger for industrial fixtures, jigs, and mechanical assemblies requiring a 5\/8-11 threaded non-locking pull ring plunger.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by threading the PRSN625 into a pre-tapped 5\/8-11 hole using the 0.62-inch hex for wrench engagement. Ensure the mating threaded bore is clean and free of debris before installation. De-energize or lock out any powered equipment before servicing assemblies that incorporate this plunger. Do not exceed the rated end force range by substituting springs or modifying the plunger body.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.56 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 1.25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Diameter\u003c\/strong\u003e: 0.38 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.44 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length\u003c\/strong\u003e: 1.31 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.69 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.31 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.62 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Type\u003c\/strong\u003e: Non-Locking\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\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: VLIER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: PRSN625\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51963260174642,"sku":"PRSN625","price":36.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/48f891635dc0b8b6a0e13bf07d090525_2e94e9a1-65fd-4bfc-a737-cdcf5b53036e.jpg?v=1789948275","url":"https:\/\/voomisupply.com\/products\/vlier-prsn625-pull-ring-plunger-5-8-11-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
