National Marker N221051 Zinc Eye Bolt with Hex Nut

Product Description

The NATIONAL MARKER N221051 is a zinc-plated steel wire eye bolt supplied with an assembled hex nut, part of the 2160BC catalog series. The eye bolt features machine screw threads and ships fully assembled with the hex nut, ready for immediate installation. Sized at 3/16 inches in diameter and 1-1/2 inches in length, it is suited for light-duty fastening, hanging, and anchoring tasks in both residential and industrial settings. The zinc plating provides a basic layer of corrosion resistance for use in interior and exterior environments. Installation requires no special tooling beyond a standard wrench or pliers.

This eye bolt is designed for general-purpose home and industrial applications where a looped anchor point is needed. Its exterior-rated zinc finish makes it a practical choice for outdoor mounting situations as well as indoor hardware assemblies. Tradespeople, maintenance technicians, and knowledgeable DIYers commonly use this fastener when securing cable, wire rope, hooks, or similar rigging hardware to structural surfaces.

Installation Notes

Installation should be performed by a qualified tradesperson or experienced installer familiar with load ratings and anchoring requirements for the intended application. Ensure the mounting surface is structurally sound and capable of supporting the intended load before installing the eye bolt. Use a standard wrench to tighten the hex nut securely after threading the bolt into position. Do not exceed the rated load capacity of the fastener or use it as a primary life-safety anchor without verifying applicable load standards.
