National Marker N221226 Zinc Eye Bolt with Hex Nut

Product Description

The NATIONAL MARKER N221226 is a zinc-plated eye bolt with a pre-assembled hex nut, part of the 2160BC catalog series. It measures 5/16 inches in diameter by 4 inches in length and features machine screw threads for secure fastening. Manufactured from steel wire with a zinc finish, this eye bolt is built to handle both interior and exterior environments where corrosion resistance and reliable load attachment points are required. It is commonly installed by contractors, maintenance technicians, and experienced DIYers across a range of home and industrial applications.

This eye bolt is suited for residential and light industrial settings where a fixed looped anchor point is needed for hanging, rigging, or routing applications. The included hex nut arrives pre-assembled for faster installation. Its zinc coating supports use in outdoor or high-moisture areas where bare steel would be prone to surface rust.

Installation Notes

Installation is typically performed by a qualified tradesperson or knowledgeable installer using hand tools such as an adjustable wrench or appropriately sized socket. Pre-drill a pilot hole to match the bolt diameter before threading into the substrate to avoid splitting or material damage. Secure the hex nut firmly against the mounting surface and verify the eye orientation before applying any load. Always confirm the substrate material and load rating are appropriate for the intended application before use.
