Eyebolts with shoulder may be loaded at other angles, but only within the plane of the loop.

• A. Fully threaded shank
• B. Partially threaded shank
• C. Shoulder
• D. Formed steel

Answer: (C)

Eyebolts with a shoulder include a bearing surface that supports the load when it’s applied at an angle in the same plane as the loop. This shoulder takes the load off the threaded shank, helping keep the eye aligned and reducing bending stress so you can apply some angular load without overstressing the connection. However, this capability is limited to angles within the plane of the loop; loading out of that plane creates a moment that the shoulder isn’t designed to handle, increasing the risk of deformation or failure. The other features described by the other options—whether the shank is fully or partially threaded or the shank’s material form—do not govern this angular loading tolerance.
