The MortorQ Spiral Drive System from Phillips Screw Co. features a recess that allows for full radial contact of the drive bit along all four wings of the recess, providing up to twice the torque of legacy drive systems. The open recess design allows for heavy coatings and paint buildup without affecting fastener driveability. Other features include lower weight and a low radar return signature. The system minimizes cam-out and reduces damage to the surrounding airframe. Its off-angle driving capability is an advantage in cramped applications.
