Abstract (en)
[origin: DE19644177A1] In socket wrenches for polygonal screw heads, a ball (16) that is located in a drillhole (13) in the wall of the wrench head (3), and is pressed elastically against the screw head by a clamping ring (7), is used to hold the screw head. In order to optimize the spring tension of the slit spring ring (7), it is proposed that the clamping ring (7) be fixed in its peripheral position so that the middle of its slit lies within the range of 40 DEG to 90 DEG , said angle being formed by the line (18) joining the center point of the screw head circumference with the midpoint of the ball, and the line (19) joining the center point of the screw head circumference with the middle of the clamping ring's slit (17).
