National Marker N221242 Zinc Eye Bolt Hex Nut 5/16 in X 6 in

Product Description

The NATIONAL MARKER N221242 is a zinc-plated steel eye bolt with hex nut, assembled and ready for installation. Part of the 2160BC catalog series, it features machine screw threads and measures 5/16 inch in diameter by 6 inches in length. The zinc plating provides corrosion resistance for both interior and exterior environments. This fastener is used by contractors, maintenance technicians, and general tradespeople in a wide range of hanging, rigging, and anchoring tasks. The included hex nut arrives pre-assembled, reducing staging time on the job site.

The N221242 eye bolt is suited for residential and light industrial applications where a threaded anchor point is needed. Common uses include hanging equipment, routing cable or rope, and securing loads to structural members. The zinc finish makes it appropriate for outdoor installations where moisture exposure is a factor. It is sold individually and is compatible with standard 5/16-inch threaded hardware and fittings.
