National Mfg N347-740 Zinc Eye Bolt with Hex Nut

Product Description

The NATIONAL MFG N347-740 is a zinc-plated steel wire eye bolt with a hex nut, sized at 3/4 inch diameter by 12 inches in length. This fastener is built for load-bearing and tie-down applications where a looped anchor point is needed. The included hex nut allows secure installation into structural members, wood framing, or threaded anchors. Standard machine screw threads run the shank on sizes up to 1/2 inch by 12 inches, while coarse machine screw threads are used on the extra-large sizes, including this 3/4 inch by 12 inch configuration. The zinc coating provides corrosion resistance suitable for both interior and exterior environments.

This eye bolt is intended for home and industrial applications where a fixed looped anchor point is required. Common uses include overhead rigging support, rope and cable routing, hanging equipment, and structural tie-down points. The 12-inch shank length accommodates deep embedment into thick lumber or structural panels. Its dual-rated suitability for interior and exterior use makes it a versatile fastener for general contractors, maintenance technicians, and tradespeople working across a range of jobsite conditions.

Installation Notes

Installation is typically performed by general contractors, maintenance technicians, or qualified tradespeople. Always verify that the mounting substrate can support the intended load before installing. Ensure the hex nut is fully threaded and tightened with the appropriate wrench to prevent backing out under dynamic or sustained loads. Follow all applicable local building codes and load-rating guidelines when using eye bolts in overhead or safety-critical applications.
