Eye Bolt 3/8″ x 4″ Zinc Plated by National Hardware – Alloy Steel

Description

Product Overview

The National Hardware N347-252 eye bolt is engineered for durability and performance across a wide range of applications. Made from high‑grade alloy steel, each bolt is zinc plated to provide excellent corrosion resistance, ensuring a long service life even in harsh outdoor conditions. The 3/8″ x 4″ size offers a robust 160 lb safe working load, making it suitable for both light‑duty household projects and more demanding industrial tasks. Its domed, round head distributes load evenly, reducing stress on the mounting surface and minimizing the risk of material fatigue. The right‑hand thread style and 2B thread class guarantee a secure fit with standard nuts and washers, while the round head design simplifies alignment during installation.

Usage

Designed for versatility, this eye bolt excels in a variety of environments. In residential settings, it can be used to hang ceiling fans, light fixtures, and decorative hardware, providing a reliable anchor point that can bear significant weight. For commercial and industrial applications, the bolt serves as a sturdy attachment for machinery, safety harnesses, and structural bracing, where its high shear strength (30‑50 ksi) ensures stability under dynamic loads. Its zinc‑plated finish makes it ideal for outdoor installations such as garden trellises, pergola supports, and marine equipment, where exposure to moisture and salt air would quickly degrade untreated steel. Installation is straightforward: simply drill a pilot hole, insert the bolt, and secure with a matching nut or washer.
