Measuring 5\/16 inches in diameter with a 1-3\/8 inch inside width and 2-1\/2 inch leg length, this Series 512 U-bolt is passivated for superior corrosion resistance and is non-magnetic, making it well suited for saltwater and high-humidity environments. It is sold in bulk packs of 5 units per package and is ready for immediate field use by marine technicians, riggers, and general contractors working in corrosive outdoor conditions.\u003c\/p\u003e\u003cp\u003eThis U-bolt is intended for marine hardware installations and other outdoor applications where atmospheric corrosion is a primary concern. Typical uses include securing pipes, cables, rods, or structural members in boat, dock, and outdoor utility installations. The passivated stainless steel construction meets the demands of repeated exposure to moisture, salt air, and weather without surface degradation. It is appropriate for both residential marine use and light commercial outdoor fastening work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePassivated stainless steel construction provides superior resistance to atmospheric and saltwater corrosion\u003c\/li\u003e\n\u003cli\u003eNon-magnetic material suits applications requiring magnetically neutral fasteners\u003c\/li\u003e\n\u003cli\u003e5\/16 inch rod diameter with 1-3\/8 inch inside width and 2-1\/2 inch leg length for precise fitment\u003c\/li\u003e\n\u003cli\u003eSeries 512 U-bolt design for consistent dimensional accuracy across the product line\u003c\/li\u003e\n\u003cli\u003eSold in bulk packs of 5 units per package for efficient job-site stocking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for marine and outdoor applications requiring stainless steel U-bolt hardware with 5\/16 inch rod diameter, 1-3\/8 inch inside width, and 2-1\/2 inch leg dimensions.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by marine technicians, riggers, or general contractors using standard hand tools. Always ensure the mounting surface and mating hardware are compatible with stainless steel to avoid galvanic corrosion. Tighten fasteners to the structural requirements of the application without over-torquing, which can stress the U-bolt legs. Follow applicable marine or building codes for fastener selection and load ratings in the specific installation environment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRod Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Width\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeg Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Passivated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMagnetic Properties\u003c\/strong\u003e: Non-Magnetic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5 units\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.77 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NATIONAL MFG\/SPECTRUM BRANDS HHI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: N222-448\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL HARDWARE","offers":[{"title":"Default Title","offer_id":51562862412082,"sku":"N222-448","price":37.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7ae699d3e6953284d1ffd53db632cff.jpg?v=1786486085","url":"https:\/\/voomisupply.com\/products\/national-mfg-n222-448-stainless-steel-u-bolt-marine-outdoor","provider":"Voomi Supply","version":"1.0","type":"link"}
