Abstract
The heads of the hammer are molded or cast from soft material and are threaded onto opposite ends of a stud extending through a disc on the handle of the hammer. A sleeve nut is welded to a hard metal plate which is captivated within each head and which prevents the sleeve nut from working loose when the hammer is used. The plate is formed with wrenching flats to enable the head to be tightened on the stud. The disc is formed by using a portion of the handle as a die in a die casting machine and is rigidly supported by an integral rod which extends into the handle.
