Abstract:
Disposable torque-limiting mechanisms with upper shank component with a torque-limiting interface, a lower shank component with a torque-limiting interface, and a washer assembly biasing element. Torque-limiting interfaces having a plurality of undulations arranged around an axial bore or drive socket and separated by a plurality of transition regions, with each undulation having an upslope, a peak, and a downslope. The torque-limiting interfaces are configured to engage and disengage to provide torque transmission with predetermined torque limits at various rotational speeds and for amounts of actuations while remaining within a specified operational range.
