  • Patent number: 5782148
    Abstract: A wrench socket has a fastener receiving recess extending inwardly from an end face of the socket. A first set of equally spaced-apart long points and a second set of equally spaced-apart short points are formed on the inner surface of the recess, each short point located between two long points. The points are parallel to the longitudinal axis of the recess. The long points extend inwardly from the end face for a length that is substantially greater than the height of the fastener element that fits within the recess while the short points extend inwardly from the end face for a length that allows axial pressure to be applied to the fastener element by the inner ends of the short points. Preferably the second set of points extend inwardly from the end face for a length that is slightly less than the height of the fastener element.
