The machine screw thread pattern ensures consistent engagement with standard fasteners and mounting hardware. Manufactured from stainless steel, this eye bolt resists corrosion in wet, coastal, or chemically exposed conditions. It is suited for use by contractors, riggers, maintenance technicians, and industrial tradespeople who require a reliable anchoring point in applications where carbon steel hardware would corrode prematurely.\u003c\/p\u003e\n\u003cp\u003eThis eye bolt is appropriate for residential and commercial installations where a threaded, looped anchor point is needed for lifting, rigging, cable routing, or equipment tie-down. The assembled hex nut allows for direct installation into a drilled and tapped surface or through a material with a nut bearing on the back face. Its stainless steel construction makes it well suited for outdoor structures, marine environments, pool equipment rooms, and other high-moisture or corrosive settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-inch diameter by 4-inch length with machine screw threads\u003c\/li\u003e\n  \u003cli\u003eAssembled with hex nut for immediate installation\u003c\/li\u003e\n  \u003cli\u003eStainless steel construction provides corrosion resistance\u003c\/li\u003e\n  \u003cli\u003ePart of the 2161BC catalog series\u003c\/li\u003e\n  \u003cli\u003eSold individually; minimum order quantity of 10 units per bulk box\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-inch machine screw thread eye bolt compatible with matching hex nuts and threaded mounting surfaces requiring a 5\/16-inch fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by contractors, riggers, or maintenance technicians using standard hand tools. Ensure the mounting substrate is rated for the intended load before installation. Torque the assembled hex nut firmly against the mounting surface to prevent loosening under dynamic or cyclical loads. Always verify applicable load ratings and local codes before using eye bolts in overhead lifting or life-safety applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Machine screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardware Included\u003c\/strong\u003e: Hex nut, assembled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.113 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00038613191266\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: N221622\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL MARKER","offers":[{"title":"Default Title","offer_id":51346951012658,"sku":"N221622","price":46.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310550396.jpg?v=1782095145","url":"https:\/\/voomisupply.com\/products\/national-marker-n221622-stainless-steel-eye-bolt-5-16x4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
