The plunger features a 1\/4-20 thread and a 0.31-inch thread length, making it straightforward to install into pre-tapped housings. With an initial end force of 0.5 lb and a final end force of 2 lb, it provides a controlled, repeatable spring-loaded engagement suitable for light-duty panel, fixture, and jig work. The pull ring allows manual retraction without tools. This part is typically installed by maintenance technicians, machine builders, and mechanical assemblers working on equipment requiring adjustable or removable stop points.\u003c\/p\u003e\u003cp\u003eThis spring plunger is suited for use in industrial machinery, precision fixtures, tooling jigs, enclosures, and positioning assemblies where a retractable stop or detent is required. The non-locking plunger type allows the plunger tip to rotate freely, reducing wear in applications where the mating surface may move laterally. The pull ring provides an accessible grip point for manual retraction in confined installations. It is appropriate for both OEM build applications and field service replacement scenarios.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 thread with 0.31-inch thread length for standard tapped-hole installation\u003c\/li\u003e\n\u003cli\u003eNon-locking plunger type allows free rotation of the plunger tip\u003c\/li\u003e\n\u003cli\u003ePull ring design enables tool-free manual retraction\u003c\/li\u003e\n\u003cli\u003eSpring end force range of 0.5 lb initial to 2 lb final for light-duty detent applications\u003c\/li\u003e\n\u003cli\u003eStainless steel construction resists corrosion in washdown or humid environments\u003c\/li\u003e\n\u003cli\u003eCompact body length of 0.44 inches suits tight-clearance assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation spring plunger for mechanical assemblies requiring a 1\/4-20 threaded pull ring plunger with non-locking action and stainless steel construction.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a pre-tapped 1\/4-20 hole in the mating component. Use a 0.25-inch hex wrench to seat the plunger body to the appropriate depth. Ensure the housing material is rated for the thread engagement required and that the plunger tip aligns with the mating detent surface before final tightening. De-energize or secure any moving equipment before servicing assemblies that contain spring plungers.\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: 0.31 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Type\u003c\/strong\u003e: Non-Locking\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\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\u003eRing Diameter\u003c\/strong\u003e: 0.62 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\u003eInitial End Force\u003c\/strong\u003e: 0.5 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 2 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: SPR25A-PT-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51718374326578,"sku":"SPR25A-PT-G","price":22.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7abf6e1d7214959c876593086840b2de.jpg?v=1788552657","url":"https:\/\/voomisupply.com\/products\/gibraltar-spr25a-pt-g-pull-ring-plunger-1-4-20-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
