The plunger features a 1\/4-20 thread size with a thread length of 0.31 inches and a non-locking design that allows smooth, repeatable engagement and release via the pull ring. Initial end force is 0.5 pounds, building to a final end force of 2 pounds, making it suited for light-duty holding and detent work. Stainless steel construction resists corrosion in washdown and outdoor environments. Machinists, millwrights, and assembly technicians install this type of component during equipment setup and fixture fabrication.\u003c\/p\u003e\u003cp\u003eThis pull ring plunger is used in jigs, fixtures, machine guards, panels, and positioning mechanisms where manual retraction of the plunger is required without tools. The non-locking plunger type allows the operator to pull the ring to retract the plunger and release it to engage, making it well suited for repetitive-cycle production equipment and adjustment mechanisms. It is appropriate for both light industrial and commercial assembly applications where stainless steel is specified for hygiene or corrosion resistance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 thread size with 0.31 inch thread length for standard tapped-hole installation\u003c\/li\u003e\n\u003cli\u003eNon-locking pull ring plunger allows tool-free manual retraction\u003c\/li\u003e\n\u003cli\u003e0.5 pound initial end force to 2 pound final end force for light-duty detent applications\u003c\/li\u003e\n\u003cli\u003ePlunger diameter of 0.16 inches with 0.19 inch plunger projection\u003c\/li\u003e\n\u003cli\u003eStainless steel construction for corrosion resistance in washdown and outdoor environments\u003c\/li\u003e\n\u003cli\u003eCompact body length of 0.44 inches for use in tight clearance applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4-20 threaded pull ring plunger for use in any fixture, jig, or mechanical assembly requiring a non-locking stainless steel spring plunger with pull ring retraction.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a tapped 1\/4-20 hole in the mating component. Thread the plunger body in by hand or with a 0.25 inch hex wrench until seated to the desired depth; do not overtighten, as the spring mechanism can be damaged by excessive torque. Confirm plunger projection and ring clearance before final installation. Power down or de-energize any adjacent electrically active equipment before working on assemblies that incorporate this component.\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\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\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\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\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: No\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-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51710581866802,"sku":"SPR25A-G","price":25.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3dacb936a6702f9d8c2fc30b22500c28.jpg?v=1788468428","url":"https:\/\/voomisupply.com\/products\/gibraltar-spr25a-g-pull-ring-plunger-1-4-20-stainless","provider":"Voomi Supply","version":"1.0","type":"link"}
