Although not as common or popular as Regular Eye Nuts, these heavy-duty eye nuts are just right for high loads and serious stress. They have a beefy collar and thicker bail that produces a higher Working Load Limit that normal. Drilled and tapped with standard UNC threads. Standard finish is self-colored as opposed to galvanized or zinc-plated. Safety factor of 5:1. For use in vertical pulls only. For angular lifts, consider one of our many Hoist Ring options.
