The electrical connectors according to embodiments of the present invention include an elongated conductor body having an external contact surface, and a clamping device including a nut plate that spans the contact surface and carries a clamping screw for securing a threaded stud terminal to the contact surface. The nut plate and the conductor body are segments cut from stocks of metal extrusions. The body extrusion has one or more longitudinal ribs that are converted by coining into one or more rows of teeth that mesh with the stud terminal to block shift of the connector along the stud terminal.
