The plunger features a 1\/2-13 thread size with a thread length of 0.41 inches and a non-locking design, allowing the plunger to be manually retracted via the pull ring without tools. The plunger diameter measures 0.31 inches with a projection of 0.38 inches, and end force ranges from 1 pound initial to 4 pounds final, providing reliable spring-loaded engagement. Machined from stainless steel, this plunger is suited for corrosion-resistant applications in wet, food-processing, or outdoor environments. Mechanical assemblers and maintenance technicians commonly install this type of hardware in fixtures, panels, and equipment enclosures.\u003c\/p\u003e\u003cp\u003eThe SPR50-G is used in light-duty to medium-duty mechanical assemblies where a spring-loaded detent or stop point is required. Typical installations include jig and fixture work, machine tool panels, enclosure latching, and equipment positioning systems. The pull ring allows manual retraction without a separate tool, making it well suited for applications requiring frequent adjustment or repeated cycling. It fits standard threaded holes or can be installed into a tapped bore with appropriate clearance for the body and head.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNon-locking pull ring design allows tool-free manual retraction\u003c\/li\u003e\n\u003cli\u003e1\/2-13 thread size with 0.41-inch thread length for secure installation in tapped bores\u003c\/li\u003e\n\u003cli\u003eSpring end force rated from 1 pound initial to 4 pounds final for consistent detent engagement\u003c\/li\u003e\n\u003cli\u003eStainless steel construction provides corrosion resistance in demanding environments\u003c\/li\u003e\n\u003cli\u003ePlunger diameter of 0.31 inches with 0.38-inch projection for positive positioning\u003c\/li\u003e\n\u003cli\u003eCompact body length of 0.81 inches suits space-constrained assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-thread pull ring plunger for use in any mechanical assembly or fixture accepting a 1\/2-13 threaded plunger body.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a tapped hole sized for 1\/2-13 threads. Use a wrench on the 0.5-inch hex head to torque the plunger into the threaded bore; do not over-tighten, as this can compress the spring or damage the stainless body. Ensure adequate clearance around the ring diameter of 1 inch before final assembly. Depressurize or de-energize any equipment before servicing plunger hardware in live machinery.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.41 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Diameter\u003c\/strong\u003e: 0.31 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Length\u003c\/strong\u003e: 1.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.81 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.56 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 4 pounds\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: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: SPR50-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51709683269938,"sku":"SPR50-G","price":32.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b6bd3e13d4852c256c2db71f70c9bf72.jpg?v=1788459109","url":"https:\/\/voomisupply.com\/products\/gibraltar-spr50-g-pull-ring-plunger-1-2-13-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
