|---|---|---|---|
Forged Eye Bolt | High | Certified WLL | Multidirectional stress, critical applications |
Bent Wire Eye Bolts | Low | Often lacks WLL | Light, static loads, non-critical applications |
Forged eye bolts have a shoulder that helps distribute load stress. This feature increases safety during general eye bolt installation. Bent wire eye bolts do not have this advantage.
Shouldered and Non-Shouldered Eye Bolts
You need to choose between shoulder pattern eye bolts and plain pattern eye bolts based on your lifting needs. Shoulder pattern eye bolts handle heavy lifting and resist twisting. You can use them for angular lifts and demanding environments.
Plain pattern eye bolts, also called non-shouldered, work best for straight lifts and lighter loads.
Feature | Shoulder Eye Bolt | Non-Shoulder Eye Bolt (Plain Pattern) |
|---|---|---|
Load Capacity | High, for heavy lifting | Medium, for lighter loads |
Twisting Resistance | Yes, prevents twisting | No, can twist under load |
