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.
