Granted: 2022-11-29
Abstract: A fastener-installation system includes a driver to drive a fastener into a structure and includes a body and a telescoping portion that moves in a proximal direction into the body to transition the driver from a decompressed position to a compressed position. A spring biases the driver into the decompressed position. A fastener feeder holds fasteners and loads them into a loaded position. A driver head has a plurality of jaws moveable between a closed position and an expanded position when the driver transitions from the decompressed position to the compressed position. In the closed position, the jaws meet at a point forming a piercing tip to pierce material of the structure. A distal end of the piercing tip forms a non-zero angle with respect to the structure as the tip is inserted into the material of the structure.  The jaws spread apart the material when they move from the closed position to the expanded position to create a path through the material.
