Abstract
An embedded fastener having enhanced torque resistance and a method of making an embedded fastener with enhanced torque resistance comprising interposing a layer between the lead battery part and the fastener. In one embodiment an electrically conducting layer of a lead adhereable layer is applied to the exterior surface of a fastener. Next, one places the fastener with the layer of lead adhereable material in a mold and injects molten lead into mold and allows the molten lead to solidify around the layer of lead adhereable material on the fastener to thereby secure the solidified lead to the layer of lead adhereable material on the fastener to provide a battery part having a fastener therein with enhanced torque resistance.
