  • Patent number: 6662417
    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.

  • Patent number: 6557219
    Abstract: A swivel hook is described that is comprised of a hook body and a swivel connector. The hook body has a generally uniform thickness and is stamped from a sheet of material. A hook member formed at a first end and a longitudinally oriented stem, having a generally rectangular cross-section, formed at a second opposite end of the hook body. The swivel connector is pivotally securable over the stem and formed from a forged metal. The swivel connector has a generally circular bore of a size exceeding the rectangular cross-section of the stem such that the stem may be received through the bore to secure the swivel connector to the hook body while permitting rotational movement of the swivel connector about the stem. Also described is a method of constructing a swivel hook.
