Abstract (en)
[origin: TW201813785A] A wrench-type tool that utilizes a plurality of engagement features to efficiently transfer torque to a fastener in order to rotate said fastener. The wrench-type tool includes a wrench-type torque-tool body. The wrench-type torque-tool body is the physical structure used to apply a torque force onto the fastener and includes a plurality of internal sidewalls and a plurality of engagement teeth. The plurality of internal sidewalls is radially distributed about a pivot axis of the wrench-type torque-tool body. Each of the plurality of engagement teeth is adjacently connected to a corresponding sidewall from the plurality of internals sidewalls in order to directly engage the sidewalls of the fastener. To increase the total contact surface with the fastener, a prismatic altitude for each of the plurality of engagement teeth is aligned parallel to the pivot axis. Furthermore, each of the plurality of engagement teeth is oriented towards the pivot axis.
