Phillips grants spiral drive license
Phillips Screw Company has granted a license to PennEngineering for its patented spiral drive system, MORTORQ Super, which was developed to deliver extremely high-torque capability for fasteners without risking damage to screw heads or surrounding areas.
The proprietary drive system will be integrated into various PEM fastener products and, according to PennEngineering, further advances the company's strategy to enter the threaded small-diameter screw market. New product offerings will include screws in 2mm and smaller thread sizes ideally suited for high-volume consumer and medical devices, among other applications.
Among features and benefits, the system's novel geometric spiral design maximises recess wall and driver contact to provide extremely high torque transfer without cam-out. The drive's low-profile head and high-strength shallow recess additionally contribute to reducing overall fastener weight.
The original Phillips drive system was introduced in the 1930s and continues to supply a cost-effective drive solution in many fastening applications.
