If there is any possibility of an angular load, which type of eye bolt should be used?

• A. eye type
• B. shoulder type
• C. cast type
• D. standard eye bolt

Answer: (B)

When a load could come in at any angle, you want the lifting point to resist bending and keep the load aligned with the bolt. A shoulder type eye bolt provides a bearing surface that seats against the load surface, which helps transfer the load along the bolt’s axis and reduces the bending moment on the eye. This design minimizes deformation or failure from off-axis loading, making it the safer choice when angular loads are possible. In contrast, a standard or eye-type bolt is mainly meant for straight pulls; applying an angle creates a bending force on the eye and can lead to deformation or failure. Cast eye bolts can be more brittle and aren’t as reliable for angular loading as a properly designed shoulder eye bolt. So, for any possibility of an angular load, use a shoulder type eye bolt.
