  • Torque limiting handle
    Patent number: 7127955
    Abstract: A torque limiting tool including an inner handle having a tool coupling portion, a biasing assembly aperture, and at least one radially oriented slot. At least one interface member is located in the radially oriented slot. The interface member includes an elongated surface generally oriented along a longitudinal axis. A biasing assembly is located in the biasing assembly aperture to provide a longitudinal biasing force that biases the interface member radially outward. An outer handle having an inner surface limits radial displacement of the interface member. The interface members are displaced radially inward when a torque applied to the inner handle exceeds a threshold value.
