High-Quality Shoulder Nut Eye Bolts

What is a Shoulder Nut Eye Bolt?

Forged shoulder nut eye bolts are heavy-duty lifting fasteners specifically designed to handle both angled lifting and straight vertical lifting applications. Unlike standard, unshouldered eye bolts, they feature a reinforced structural shoulder base that must be installed completely flush with the mounting surface to ensure maximum stability and safety during heavy load transfers.

Working Load Limits and Installation Guidelines

When utilizing shoulder eye bolts for heavy-duty rigging and lifting, it is critical to adhere to strict installation and load limit guidelines to maintain a safe work environment:

• Flush Mounting: The shoulder of the eyebolt must sit perfectly flush against the mating surface to prevent the shank from bending under pressure.
• Vertical Lifts: The advertised maximum working load limits apply exclusively to straight, vertical lifts.
• Angled Lifts: While they are engineered to accommodate angled pulls, lifting at an angle (up to a strict 45-degree maximum) significantly reduces the overall working load limit of the fastener.

Available Materials and Customization

To accommodate a wide range of indoor and severe outdoor lifting environments, U-Bolt-It manufactures these reliable forged fasteners using several highly durable, industrial-grade materials. Based on your project's environmental demands, our shoulder nut eye bolts are available in plain steel, hot-dipped galvanized steel for enhanced outdoor wear, or highly corrosion-resistant stainless steel for marine applications.
