National Marker N347-666 Zinc Eye Bolt Hex Nut 5/8x6 in

Product Description

The NATIONAL MARKER N347-666 is a zinc-plated steel eye bolt with hex nut, sized at 5/8 inch diameter by 6 inches in length. It features standard machine screw threads and is manufactured from steel wire with a zinc finish for corrosion resistance. This type of fastener is used to create a fixed anchor point for rope, cable, hooks, or hanging hardware. Installation is straightforward and suited for both light industrial settings and general-purpose use. The included hex nut allows for secure tightening against the mounting surface without requiring additional hardware.

This eye bolt is suited for interior and exterior applications in industrial and residential settings. Common uses include hanging fixtures, rigging light loads, routing cable or rope through structural members, and creating anchor points on wood, metal, or masonry surfaces. The zinc plating provides a basic level of weather resistance for outdoor installations. Maintenance crews, contractors, and general tradespeople regularly use hardware of this type for both permanent installations and temporary rigging tasks.

Key Features

• 5/8 inch diameter by 6 inch length for deep-thread engagement in structural material
• Standard machine screw threads for compatibility with common hex nuts and couplings
• Zinc-plated steel wire construction for corrosion resistance in interior and exterior environments
• Includes hex nut for secure, tool-tightened installation
• Sold individually, suitable for single-point anchor applications

Compatibility

Designed as a general-purpose eye bolt for use in industrial and residential applications requiring a 5/8 inch threaded anchor point. Verify load ratings and substrate requirements before installation; this hardware is not rated for overhead lifting unless specifically certified.

Installation Notes

Install using standard hand tools including an appropriate wrench to seat the hex nut firmly against the mounting surface. Ensure the mounting substrate is structurally adequate for the intended load. Do not use this eye bolt for overhead lifting applications unless it carries a certified working load limit rating. Exterior installations should account for long-term exposure conditions even with the zinc finish present.
