· Eye Bolt Application

Loading at an angle can alter the working load limit of the eye bolt.


It is important to note that all eye bolts are designed for loading with the axis at the center of the eye. They should never be loaded perpendicular to that axis because they are likely to bend and break.

Eye Bolt Working Load Limit Effects due to Angular Loading
The degree of angle of your load can have a big effect on the working load limit of the eye bolt.

This cable is at 0 degrees. At 0 to 5 degrees, the eye bolt is rated at 100 percent of its working load limit. In this case, the catalog working load limit of this 3/8th inch eye bolt is 1,550 pounds.

At 15 degrees, the working load limit is reduced by 20% and the effective working load limit of the eye bolt becomes 1240 pounds, which is 80% of the original rated capacity.

30 degrees makes for 65% of the original rated capacity.

45 degrees makes for 30% of the original rated capacity.

90 degrees makes for 25 % of the original rated capacity. The 75% reduction in capacity makes the effective working load limit only 388 lbs.
Swivel Hoist Rings: Alternative Choice for Angular Loading

Because of the effect that angles have on eye bolts and working load limits, we recommend using swivel hoist rings as an alternative choice. The advantage to them over eye bolts is that they maintain 100 percent of the working load limit at any angle from 0 to 90 degrees.
