ABSTRACT:
An electrical contact structure for making and maintaining an electrical connection through a rotatable tool head is provided. A low cost contact probe assembly can be incorporated into the drive of various conventional tightening tools to extend onto the head of a fastener to make and maintain electrical contact therewith while the head is being operated upon by the socket or gripping means of the tightening tool. This contact probe assembly includes an insulated and shielded electrically conductive tube.
