Abstract
Disclosed is a tool head, such as a socket, having an annular groove that allows gripping of the tool head to remove the tool head from a tool having a lug, such as ratchet, torque or impact wrenches. The groove is spaced from the drive engagement end of the socket for improved gripping performance. The groove dimensions were determined to improve gripping performance as well. For example, the groove can have a depth of 0.020″-0.050″, preferably 0.020″-0.030″. More broadly, the groove can have a depth of 5.0%-15.0%, and preferably 5.0%-10.5%, of the drive end outer diameter. The groove can, either alone or in combination with the above ranges, have a width of 0.25-0.47″, preferably 0.29-0.43″. The groove can, either alone or in combination with the above ranges, begin at a distance of 0.070-0.160″, preferably 0.090-0.140″, and have an end of groove farthest from the end of the socket of 0.32-0.63″, preferably 0.38-0.57″.
