Since its introduction, TORX PLUS® Drive has consistently outperformed every other drive system. The true 0˚ drive angle virtually eliminates the radial forces and stresses. Reduced contact stress also reduces coating damage that can occur in other recess designs. The straight, vertical sidewalls of the TORX PLUS® Drive System virtually eliminates cam-out. The elliptically-based geometric configuration of the TORX PLUS® Drive System maximizes engagement between driver and fastener. Ergonomic studies demonstrate that the TORX PLUS® Drive System can reduce fatigue and muscular stress during the manual assembly of fasteners. That is because little or no end load is required to keep the driver engaged with the fastener. Its longer tool life and optimal torque transfer have enhanced product reliability, increased productivity, and reduced total assembly costs on assembly lines in a multitude of industries around the world.

For fasteners that require an organic finish, due to the coating process, the coating builds up more at the “A” lobes than at the “B” lobes. As a result, the recess was designed to accommodate the coating buildup by oversizing only the “A” dimension.

  • The A oversizeTM provides space for the coating to go without interfering with the Drive bit
  • Maintaining the “B” diameter ensures maximum drive system strength
