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.

Our team of experts is ready to support you.
  • Straight, vertical sidewalls virtually eliminate camout
  • Elliptical-based geometric configuration maximizes the engagement between driver bit and fastener recess spreading driving forces over the surface area and extending tool life
  • The system virtually eliminates the radial forces that can cause stress on fastener recesses
  • Reduce fatigue and muscular stress during manual assembly due to little to no required end load
  • Ensuring optimal torque transmission, The high torque transfer capabilities means it can utilize increased seating torques without increasing current bit usage levels. These capabilities are also important during removal of a fastener in service environments, where corrosion can cause seizing in the joint.
  • 25% average improvement in driver bit torsional strength over TORX® Drive System.
  • 100% average improvement in driver bit life; many users of the TORX PLUS® Drive System have driven 2 to 10 times more fastener per drive tool.
  • The TORX PLUS® recess completely enclosed the driver tip, reducing tool slippage as well as costly and unsightly damage to the fastener and surrounding surfaces.
  • TORX® Drive tools can be used to remove and reinstall TORX PLUS® Drive recess fasteners in service conditions
