BATTERY CLAMP AND PROCESS FOR MAKING SAME Battery clamp including a nut molded into one of the clamping arms and a rotatable bolt with a flanged shaft molded into the other clamping arm. The head of the bolt, flange, and nut provide bearing surfaces for drawing the clamping arms together, or forcing the clamping arms apart, depending upon the rotation of the bolt. The battery clamp is manufactured in a single molding process by prethreading the nut onto the flanged bolt to a predetermined position, positioning the pre-threaded nut and bolt in one portion of a battery clamp mold, assembling the remaining pieces of the battery clamp mold around the bolt and nut, securing the pieces of the battery clamp mold together, pouring lead or a lead alloy into an opening in the battery clamp mold, quenching the lead filled mold in a liquid bath to accelerate the cooling process, separating the secured mold pieces after the lead or lead alloy cools, and removing the molded battery clamp.
