For decades aerospace designers have had to compromise on fastener performance... shallow head styles like the dovetail slot had poor torque transfer and damaged easily while robust drives  like hex heads required thicker material and added weight. Now the MORTORQ ® spiral drive system provides a true high performance solution. The unique shape provides full contact of the driver over the entire recess wing resulting in extremely high torque capability without the risk of damage. Depth of the recess in the fastener head is minimized resulting in ultimate torque performance in 100º flush head and shear head applications.

The open recess concept allows driver to recess misalignment and compensates for paint buildup without degrading torque capability. Workers can easily install and remove panel and structure fasteners at odd angles without high muscle stress or fear of damage to surrounding surfaces. Larger driver cross-sections and curved surfaces provide extended tool life and resistance to tensile fatigue fracture when used with high load pulse tools. Acoustic and radar return is minimized by the unique recess profile.
