Abstract
A passive locking chuck for a rotary driver. The chuck receives the driving end of a foundation component such a screw anchor to be driven into the ground. As the driving end is inserted into the chuck, spring biased pawls are displaced until insertion is complete. The geometry of each pawl dictates that less force is required to insert the foundation component than to remove it. The chuck has a geometry that mates with the geometry of the driving end of the foundation component.
