Under angular pulls, shouldered eyebolts require what adjustment to their rated load?

• A. Derate the load
• B. Increase the load
• C. No change
• D. Only derate under certain temperatures

Answer: (A)

Eyebolts are rated for axial loads along the bolt’s centerline. When the pull is angular, the force no longer acts straight through the eye, creating a bending moment and extra stress on the eye and threads. This reduces the bolt’s effective strength, so the rated load must be reduced to maintain a safe margin. The derating accounts for the off-axis load and keeps the lift within safe limits. The other options don’t fit because increasing the load ignores the extra stresses from angle, and no change would be unsafe for angular pulls. Derating does not depend on temperature alone in this context.
