Tap-Fix® Thread Rolling Screws, by utilising the three lobed thread form, require a low level of assembly torque to initiate thread forming.  Further benefits: Tap-Fix® Screws form a female thread capable of accepting a standard machine screw thread form should the need arise.  The three lobed thread design allows the displaced parent material to cold flow into the relief areas of the screw thereby increasing the resistance to vibration and loosening of the screw.
