Each bolt features a closed-loop eye designed for attaching cables, ropes, hooks, or rigging hardware to a fixed surface. Stainless steel construction provides corrosion resistance in wet, outdoor, or marine-adjacent environments where carbon steel fasteners would degrade. Each unit ships with a matching hex nut for secure through-bolt or anchored installation. This SKU is sold in a box of 10 units.\u003c\/p\u003e\n\u003cp\u003eThis eye bolt is suited for light rigging, hanging, tie-down, and anchoring applications in residential and light commercial settings. Typical uses include securing rope lines, hanging equipment, or anchoring load-bearing fixtures to wood framing, structural members, or similar substrates. Installation is performed by general contractors, maintenance technicians, or experienced DIYers. The 160-pound load rating makes this appropriate for moderate static loads rather than dynamic or overhead lifting applications without further engineering review.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch diameter by 4 inch length for deep engagement in structural substrates\u003c\/li\u003e\n  \u003cli\u003eStainless steel construction resists corrosion in outdoor and high-moisture environments\u003c\/li\u003e\n  \u003cli\u003e160-pound load capacity for moderate static anchoring and tie-down applications\u003c\/li\u003e\n  \u003cli\u003eIncludes matching hex nut for secure, flush installation\u003c\/li\u003e\n  \u003cli\u003eSold in a pack of 10 units for multi-point installations or stock replenishment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/8 inch eye bolt for use in wood, structural framing, and similar substrates where a threaded fastener with an attachment loop is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall by drilling a pilot hole appropriate for a 3\/8 inch bolt thread before driving into wood or soft substrates to prevent splitting. Secure the hex nut firmly against the mounting surface to prevent loosening under load. Always verify that the substrate and mounting point are rated to support the intended load before use. This fastener is intended for static load applications and should not be used as a certified lifting point without a load engineer review.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLoad Capacity\u003c\/strong\u003e: 160 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Hardware\u003c\/strong\u003e: Hex Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10 units\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.7 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\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: NATIONAL MFG\/SPECTRUM BRANDS HHI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: N221-648\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL HARDWARE","offers":[{"title":"Default Title","offer_id":51559231684914,"sku":"N221-648","price":49.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f479eb0cca132f630af61e67146a115.jpg?v=1786429946","url":"https:\/\/voomisupply.com\/products\/national-mfg-n221-648-ss-eye-bolt-3-8x4-in-160lb-10pk","provider":"Voomi Supply","version":"1.0","type":"link"}
