This fastener is used to create a secure anchor point for rope, cable, wire, or chain in light-duty rigging and tie-down applications. The zinc finish provides corrosion resistance for general indoor and light outdoor use. Installers in plumbing, HVAC, electrical, and general mechanical trades use eye bolts like this to hang conduit, support piping, or anchor straps and safety lines.\u003c\/p\u003e\n\u003cp\u003eThis eye bolt is suited for residential and light commercial applications where a threaded anchor point is needed in wood, metal, or structural members. Typical uses include hanging pipe runs, suspending ductwork supports, securing cable trays, and general fastening tasks. It ships in a bulk pack of 10 units, making it practical for job-site stocking.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch diameter x 8 inch length for deep thread engagement in structural members\u003c\/li\u003e\n  \u003cli\u003e160-pound load capacity for light-duty rigging and suspension tasks\u003c\/li\u003e\n  \u003cli\u003eZinc plating provides corrosion resistance for general-use environments\u003c\/li\u003e\n  \u003cli\u003eBulk pack of 10 units per package for job-site convenience\u003c\/li\u003e\n  \u003cli\u003eStandard threaded shank compatible with common nuts and hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose threaded eye bolt suitable for use in wood or metal substrates where a 3\/8 inch anchor point is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eEye bolts should be installed by a qualified tradesperson using appropriate hand tools and torqued until the eye is seated firmly against the mounting surface. Always verify that the load direction aligns with the plane of the eye to avoid side-loading, which reduces rated capacity. Shut off or de-energize adjacent systems before drilling or fastening near live electrical or mechanical equipment. Confirm the substrate material and thickness can support the rated load before use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLoad Capacity\u003c\/strong\u003e: 160 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\/Finish\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10 per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 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: N221-291\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL HARDWARE","offers":[{"title":"Default Title","offer_id":51563953750322,"sku":"N221-291","price":21.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc9fc8ffe01314542a344b6ee943678c.jpg?v=1786507752","url":"https:\/\/voomisupply.com\/products\/national-mfg-n221-291-zinc-eye-bolt-3-8x8-inch-160lb","provider":"Voomi Supply","version":"1.0","type":"link"}
