The plunger uses a non-locking design with a pull ring for manual retraction without tools. It threads into a tapped hole using a standard 1\/4-20 thread and delivers an initial end force of 0.5 pounds and a final end force of 2 pounds, making it well-suited for light positioning work where repeatable, spring-loaded engagement is required. Machinists, maintenance technicians, and machine builders install these plungers in fixtures, jigs, panels, and equipment enclosures.\u003c\/p\u003e\n\u003cp\u003eThis pull ring plunger is used in industrial machinery, fabrication fixtures, control panel assemblies, and tooling setups where a manually retractable spring plunger is needed. The pull ring allows the plunger to be retracted by hand without a separate tool, streamlining operation in repetitive positioning tasks. It is a direct-install component suited for both OEM assembly and field maintenance on equipment requiring 1\/4-20 threaded plunger positions.\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\u003e1\/4-20 thread for installation into standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in mechanical assembly applications\u003c\/li\u003e\n  \u003cli\u003eInitial end force of 0.5 pounds to final end force of 2 pounds for light positioning loads\u003c\/li\u003e\n  \u003cli\u003eCompact body length of 0.44 inches suits space-constrained assemblies\u003c\/li\u003e\n  \u003cli\u003eHex drive head for installation and torque control with standard tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any mechanical assembly or fixture requiring a 1\/4-20 threaded non-locking spring plunger with a pull ring for manual retraction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by maintenance technicians, machinists, or assemblers using a standard wrench or hex key on the 0.25-inch hex head. De-energize or lock out any associated equipment before installing or replacing plungers in live machinery per applicable LOTO procedures. Do not overtighten; thread engagement into the tapped hole should be confirmed before applying final torque. Ensure the mating bore is clean and free of debris to allow full plunger travel.\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\u003eInitial End Force\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Diameter\u003c\/strong\u003e: 0.16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.19 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length\u003c\/strong\u003e: 0.62 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.44 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.31 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.31 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Diameter\u003c\/strong\u003e: 0.62 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Type\u003c\/strong\u003e: Non-Locking Pull Ring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: None\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: PR25A-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51694662222130,"sku":"PR25A-G","price":21.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/99772d62dfe7de4ac2c839a0c1eeabee.jpg?v=1788326839","url":"https:\/\/voomisupply.com\/products\/gibraltar-pr25a-g-pull-ring-plunger-1-4-20-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
