Eye Bolt

What is Eye Bolt?

An eye bolt is a threaded fastener with a looped head used for lifting, rigging, or securing loads in construction.

Description

An eye bolt is a type of fastener featuring a threaded shank and a closed loop, or “eye,” at one end. It is designed to provide a secure attachment point for ropes, cables, chains, or hooks used in lifting, anchoring, or tensioning applications.

In construction and industrial settings, eye bolts are commonly used for rigging, material handling, fall protection systems, and equipment anchorage. They are manufactured in various types—including plain eye bolts, shoulder eye bolts, and machinery eye bolts—each suited to different load directions and capacities. Material selection, such as carbon steel, stainless steel, or galvanized steel, depends on load requirements and environmental exposure.

Proper installation and loading are critical for eye bolt safety. Eye bolts must be installed to the correct depth, aligned with the direction of the load, and rated for the intended forces. Shoulder eye bolts are required for angular or side loading, while non-shouldered eye bolts are typically limited to straight, in-line pulls. Following manufacturer ratings and safety standards helps prevent failure and job site accidents.

FAQs

  • What is an eye bolt used for?

    It is used to provide a secure attachment point for lifting, rigging, or securing loads.

  • What is the difference between a shoulder and non-shoulder eye bolt?

    Shoulder eye bolts are designed for angled loads, while non-shoulder eye bolts are for straight vertical loads only.

  • Can eye bolts be used for overhead lifting?

    Yes, if they are properly rated, installed, and used according to load direction requirements.

  • What materials are eye bolts made from?

    Common materials include carbon steel, stainless steel, and galvanized steel.

  • Do eye bolts have load ratings?

    Yes, eye bolts are rated for specific working load limits that must not be exceeded.

Fun Fact

Shoulder eye bolts can safely handle angled loads—but their capacity drops significantly as the angle increases, sometimes by more than 50%.
