What angle is NOT recommended for eyebolts?

• A. 25°
• B. 50°
• C. 75°
• D. 95°

Answer: (D)

Eyebolts are rated for a pull that is along their axis. When you introduce an angle to the lift, the force is no longer purely axial and the bolt experiences bending stresses as well as shear on the threads. This reduces the effective capacity of the eyebolt, and the published ratings aren’t valid for deflected loads once you go past a perpendicular or near-perpendicular pull. So, as the angle increases beyond 90 degrees the risk grows and the rating becomes unreliable. Angles like 25°, 50°, and 75° keep the force closer to axial, maintaining the eyebolt’s rated strength, while 95° is not recommended because it creates unsafe loading conditions.
