TORX® features a star-formed, elliptically-primarily based geometry with 6 rounded lobes. The TORX® can be utilized to transfer a higher torque when compared to the classical screw profiles with no damaging bit or screw. Due to the lower radial forces, the tool life of both screw and driver is prolonged. The small radial forces certainly are a results of the circular geometry on the lobes, the straight, vertical sidewalls and the push-angle of just fifteen degrees.
The hex socket screw push incorporates a hexagonal recess and will be driven by a hex (Allen) wrench, hex screwdriver or hex bit. Their lever arch mechanisms allows for greater tightening torque, and Call surfaces with the fastener are protected against external hurt.
