a hook having a body portion with a first end and a second end, the body portion extending along a curve to a tip disposed at the second end, the body having a neck portion disposed in spaced apart relation to the tip such than an opening is formed between the tip and the neck portion;
a pair of opposed members disposed at the first end of the hook, the pair of opposed members defining a space therebetween, the opposed members disposed in spaced apart facing relation, the opposed members each having a first opening sized to receive a load pin configured to attach the hook to a wire or rope of a crane or hoist;
wherein the load pin is inserted through the first opening in one of the pair of opposed members and extends across the space and into the first opening of the other of the pair of opposed members where it extends through the first opening in an axial direction such that there is a space inside the first opening in one of the pair of opposed members behind the load pin; and,
an axial device disposed inside the first opening in one of the pair of opposed members and positioned behind the load pin when the load pin is inserted into the first opening of one of the pair of opposed members and extends across the space into the first opening of the other opposed member,, wherein the first opening on one of the pair of opposed members extends through one of the pair of opposed members at a substantially constant diameter and wherein the pair of opposed members do not contain any transverse openings intersecting with the first opening; and,, wherein the axial device is a knurled plug.
