A double-ended ratcheting box end wrench includes a body formed entirely of glass-fiber-reinforced plastic material with box-type ratcheting inserts molded at opposite ends of the body. The body includes layers of random discontinuous glass-fiber-reinforced plastic material and a band of unidirectional continuous glass-fiber-reinforced plastic material. The body is subjected to a compression molding process embedded within which are the ratcheting inserts to form a composite wrench structure. Each insert includes a two-part housing in which are disposed a ratchet gear, a pawl and a bias spring.
