ABSTRACT:
A wrench includes a handle, a head formed at an end of the handle for engagement with a nut and a magnet embedded in the head. In an aspect, the head includes an intermediate portion and two jaws extending from the intermediate portion. The magnet is embedded in the intermediate portion or one of the jaws. Alternatively, a magnet is embedded in each of the jaws. In another aspect, the head is a ring for engagement with the nut. The magnet is embedded in the ring or includes a first tip embedded in the ring and an exposed second tip. Thus, the second tip of the magnet performs as a stop for the nut. In another aspect, the wrench is a quick-release wrench. The intermediate portion includes two surfaces for contact with two adjacent facets of the nut. The magnet is embedded in one of the surfaces of the intermediate portion. Another magnet may be embedded in the remaining one of the surfaces of the intermediate portion. In another aspect, the wrench is an adjustable wrench including a handle, a fixed jaw projecting from the handle and a movable jaw mounted thereon. The movable jaw can be moved toward and away from the fixed jaw by operation of a worm and rack mechanism. The magnet is embedded in the fixed jaw or movable jaw. In another aspect, the head includes facets for contact with facets of the nut. The magnet is embedded in one of the facets of the head.
