ABSTRACT:
The present invention is a hoist ring provided with a central screw having a screw head at one end and a threaded shank at an opposite end. A washer is provided between the screw head and a lower bushing, with the lower bushing being secured on the screw with a self-lock retaining ring which inserts into a lower recess provided in the lower bushing. The self-lock retaining ring is provided with teeth for gripping the threaded shank. An upward oriented sleeve provided on the lower bushing extends upward to the washer. A body rotatably mounts around the sleeve by means of an axial bore provided in the body. A bail pivotally mounts to the body on an axis transverse to an axis of the lower bushing by means of shoulder pins which insert into horizontal bores of the body and which are secured therein by roll pins. The roll pins insert through vertical bores in the body and through aligned holes in the shoulder pins and are held in place by the washer and lower bushing. The bail is attachable to a load and the threaded shank is attachable to a base.
