National Marker N221234 Zinc Eye Bolt Hex Nut 5/16x5 in

Product Description

The NATIONAL MARKER N221234 is a 5/16-inch by 5-inch zinc-plated eye bolt with an assembled hex nut, built for load-bearing anchor and attachment tasks in both residential and industrial settings. The eye bolt features machine screw threads and ships pre-assembled with the hex nut, reducing prep time on the job. Manufactured from steel wire and finished with a zinc coating for corrosion resistance, this fastener is suited for indoor and outdoor use. At 0.126 pounds, it is a lightweight component that handles typical hanging, rigging, and tie-down applications where a threaded eye anchor is required.

The N221234 is appropriate for a wide range of general fastening applications including hanging fixtures, anchoring cables, and securing loads to structural surfaces. Its design makes it equally at home in residential projects such as garage or shed installations and in light industrial environments where a reliable threaded eye anchor point is needed. Interior and exterior rated, the zinc finish helps the fastener hold up against moisture and mild environmental exposure.

Installation Notes

Installation is typically performed by carpenters, maintenance technicians, or general contractors. Before installation, confirm the receiving material and structural member are rated for the intended load. Use a properly sized wrench to seat the hex nut firmly against the mounting surface without over-torquing the threads. Follow applicable local building codes and load-rating guidelines when using eye bolts for rigging or overhead hanging applications.
