What type of eyebolt must be used when an angular load is applied?

The shouldered eyebolt is specifically designed to handle loads that are applied at an angle, which is crucial when working with rigging. This type of eyebolt features a shoulder that provides additional support and minimizes the risk of bending or breaking under angular loads. Using a shouldered eyebolt ensures that the load is distributed evenly, reducing the potential for failure and enhancing safety during lifting operations.

In contrast, other types of eyebolts may not provide the same level of support under angular loads. Standard eyebolts, for instance, are typically meant for vertical loading and may not perform adequately when the load is not aligned directly above them. Cylindrical and heavy-duty eyebolts also lack the specific design elements that promote safety and efficiency when dealing with angular tensions. Thus, for applications where angular loads are present, a shouldered eyebolt is the appropriate choice to ensure safe and effective rigging practices.
