Part of the 2160BC catalog series, it features machine screw threads and ships ready to install. The zinc plating provides corrosion resistance for both interior and exterior environments. Manufactured from steel wire, this fastener is suited for light rigging, hanging, and anchoring tasks in residential and light industrial settings. Licensed tradespeople and general contractors reach for this hardware when a secure, looped anchor point is needed on a structure or fixture.\u003c\/p\u003e\n\u003cp\u003eThe N221267 is designed for a wide range of home and industrial applications. Its assembled configuration — eye bolt plus hex nut — makes it practical for quick installation in wood, metal, or composite substrates. Interior uses include hanging fixtures, cable management, and equipment anchoring. Exterior uses benefit from the zinc coating, which resists rust and oxidation in exposed conditions. The 3\/8-inch thread diameter and 4-inch shank length make it appropriate for moderate load applications where a through-bolt or lag installation is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eZinc-plated finish for corrosion resistance in interior and exterior applications\u003c\/li\u003e\n  \u003cli\u003eMachine screw threads with hex nut included and pre-assembled\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch thread diameter and 4-inch shank length\u003c\/li\u003e\n  \u003cli\u003eManufactured from steel wire for reliable tensile strength\u003c\/li\u003e\n  \u003cli\u003ePart of the 2160BC catalog series for consistent cross-reference ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose eye bolt for residential and light industrial fastening applications where a 3\/8-inch by 4-inch zinc-plated machine-thread anchor point is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by carpenters, electricians, riggers, or general contractors depending on the application. Always drill a properly sized pilot hole before driving the bolt to avoid splitting or cracking the substrate. Ensure the hex nut is tightened securely against the mounting surface and that the load is applied in line with the eye axis to avoid side-loading. Verify that the substrate material and thickness are rated for the intended load before use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel wire, zinc-plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Machine screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardware Included\u003c\/strong\u003e: Hex nut, assembled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Interior and exterior\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.173 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCatalog Series\u003c\/strong\u003e: 2160BC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUOM\u003c\/strong\u003e: Each\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 MARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: N221267\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL MARKER","offers":[{"title":"Default Title","offer_id":51347011928370,"sku":"N221267","price":23.17,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310550382.jpg?v=1782096454","url":"https:\/\/voomisupply.com\/products\/national-marker-n221267-zinc-eye-bolt-hex-nut-3-8x4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
