Abstract
A method of constructing a swivel hook. The method comprises the steps of: forming a hook body by way of a stamping process; forming a swivel connector by means of a forging process; placing a first washer having a rectangular shaped right angled bore over a rectangular stem on the hook body; inserting the rectangular stem of the hook body through a circular bore in a first end of the swivel connector; placing a second washer having a generally rectangular shaped right angled bore over the rectangular stem of the hook body and into abutment with the swivel connector such that the end of the stem extends through the second washer; and, thereafter, peening the tip of the rectangular stem extending through the second washer to secure the second washer in place over the rectangular stem.
