SPS Technologies MORTORQ® Fasteners Deliver Higher Torque, Lower Maintenance, Lighter Weight

February 4 , 2005

JENKINTOWN, Pa. – SPS Technologies, an official licensee of the MORTORQ® Drive System developed by the Phillips™ Screw Company, offers a range of aerospace fasteners featuring the unique drive system. The MORTORQ drive system is engineered to deliver a solution to the problem of poor torque transfer. Its proprietary shape provides full contact of the driver to the entire recess in the screw or bolt, resulting in high torque capability while minimizing the risk of damage to the fastener.

MORTORQ fasteners offer a labor-saving, lighter weight alternative to using easily damaged shallow head fasteners with poor torque transfer and robust drives that require thicker material and added weight. The more shallow counter bore required with MORTORQ fasteners’ lower profile head can reduce material thickness, and thus weight, in many joint designs.

According to SPS, the depth of the fastener recess is reduced, allowing increased torque transfer in 100° and 130° flush head fasteners, as well as other MORTORQ bolts and screws offered by SPS for shear and other applications.

The open recess concept allows the driver to recess misalignment and compensates for paint buildup without degrading torque performance. Workers can easily install and remove MORTORQ panel and structure fasteners at odd angles without high muscle stress or fear of damage to surrounding surfaces.

The MORTORQ system’s larger driver cross-sections and curved surfaces provide extended tool life and resistance to tensile fatigue fracture when used with automated equipment. In aerospace applications, acoustic and radar return is minimized by the unique recess profile.

SPS Aerospace Fasteners is a leading developer, manufacturer and global supplier of the most comprehensive line of aerospace fasteners and precision components. SPS® products are used in commercial and military aircraft, jet engines and other critical applications.
