Abstract
A ratchet wrench in which the body and an integrally formed handle are of molded plastics material. The body includes a head formed with an opening which contains the ratchet mechanism. A metal bar embedded in the handle during the plastics molding process substantially enhances the physical strength of the wrench, and metal clamp plates overlying and seated in recesses in opposed principal surfaces of the wrench are bolted to each other, and are coupled to internal core components in the head of the wrench to secure the ratchet mechanism in place. The metal bar in the handle imparts structural stability and integrity as well as increased mechanical strength to the composite assembly.
