National Marker N347-674 Zinc Eye Bolt Hex Nut 5/8x8 in

Product Description

The NATIONAL MARKER N347-674 is a zinc-plated steel eye bolt with hex nut, sized at 5/8 inch diameter by 8 inches in length. It uses standard machine screw threads and is manufactured from steel wire with a zinc finish for corrosion resistance. This fastener is suited for lifting, rigging, and tie-down applications across industrial and residential settings. Licensed tradespeople and experienced DIYers install these eye bolts where a secure anchor point is needed on a structural surface. The included hex nut allows for flush or flush-to-surface mounting without sourcing separate hardware.

This eye bolt is appropriate for both interior and exterior applications, including use on wood framing, steel structures, and overhead mounting surfaces in warehouses, workshops, garages, and residential settings. The zinc coating provides moderate corrosion resistance, making it suitable for covered outdoor use. Standard machine screw threading allows compatibility with common nuts and threaded hardware of matching pitch and diameter.

Compatibility

Installation Notes

Installation is typically performed by qualified tradespeople or experienced general contractors following applicable building and rigging codes. Before installation, confirm the receiving material (wood, steel, or concrete with appropriate anchor) is rated to handle the intended load. Use a properly sized wrench to tighten the hex nut securely against the mounting surface. Never exceed the rated load capacity of the eye bolt or the mounting substrate.
