Angular lifting at up to 45° is allowable in this direction (plane of the eye) but load rating is reduced.
Only straight lifting is allowable in this direction.
Lifting Eyes should be inspected before each use for possible defects and installed by a person trained in the installation of lifting devices. The tapped receiving hole should be countersunk, free of any debris, and deep enough to ensure proper shoulder seating. Firm hand tightening is recommended for installation; do not use wrenches or bars. Angular lifting should be avoided, because angular lifts significantly reduce rated capacity. Any angular loads must be radial in the plane of the eye, never at an angle to that plane. A steel washer or shim may be used under the shoulder to achieve proper eye orientation, but its thickness should not exceed one thread pitch. A washer may also be required to ensure flush seating on rough mounting surfaces.
