Sequential torque application retention system

A sequential torque application retention system comprising:

• a driver mechanism having a shaft with a hex shank end and a tip end opposite the hex shank end;
• a socket formed in the tip end, said socket configured to receive an insertable bit removably coupled to the socket via a set screw;
• a center drive formed by said insertable bit;
• an outboard drive formed in said tip end;
• said outboard drive including a pair of outboard drive studs set radially apart and aligned along a common radial axis of the shaft;
• a screw including a screw head;
• a central receiver formed in said screw head, said central receiver corresponding to said center drive, said central receiver configured to receive said center drive;
• a pair of outboard receivers formed in said screw head corresponding to said outboard drive, said pair of outboard receivers configured to receive each of said outboard drive studs;
• wherein said center drive is engaged with said screw head at said central receiver responsive to an initial torque and said outboard drive is engaged with said screw head at said pair of outboard receivers responsive to a subsequent torque;
• and
• wherein said outboard receivers are positioned so that they do not engage with said outboard drive responsive to the initial torque;
• wherein the insertable bit employed as the center drive includes a length dimension and a diameter dimension, being determined by a predetermined initial torque value and a predetermined subsequent torque value, such that the insertable bit flexes via torsion about the axis of the insertable bit to limit the torque applied by the central drive bit responsive to the subsequent torque while applying the subsequent torque through the outboard drive.
