ABSTRACT:
A clamping device having a U-shaped portion between which material is positioned to be mechanically and electrically coupled to the clamp when engaged. One inner surface of the U-shaped clamp includes a conically-shaped tip of a hardened material which is positioned directly opposed to a threaded bolt or stud extending outwardly from the opposed inner surface of the U-shaped clamp for engagement with the conically-shaped tip. The terminal end of the oppositely positioned threaded bolt is formed with a complementary recess and, preferably, a knurled or serrated outer edge for abrading material which is engaged upon the tightening of the bolt. In one embodiment of the clamp, the threaded bolt includes a terminal portion adapted to accommodate and have secured therein a terminated ground wire, and the U-shaped clamp has an undercut portion for positioning against an upturned flange edge of a panel. In another embodiment, the U-shaped clamp does not have the undercut portion, nor a terminal portion adapted to receive a terminated ground wire. This latter embodiment is more suitable for positively securing two flat pieces of strap material, such as two copper bars, used in forming a terminated ground connection.
