Low Clearance Drive System

External Torx Plus® Low Profile Head

External Torx Plus Rendering


Lower head height allows for clearance opportunities

Allows higher torque transfer without damage to fastener or finish

Lower head volume (weight) than hex and pan head fasteners


Domed or indented styles available with hex flange or pan head bearing surfaces

Elliptically based geometry

For applications requiring fasteners with both high torque transfer capabilities and low head height, external TORX PLUS® low-profile head fasteners are the ideal choice. They are engineered to improve performance over hex drive fasteners without added head volume.


Standard Design Guidelines

Fastener Sizes:
M0.8 to M18
(#000 to 5/8")

Drive System:
External Torx Plus Drive

Head Styles:
Dome or indented head with hex flange or pan head bearing surface

Thread Styles:
It can be used with any thread style


Hex Drive SystemThe external hex drive allows high torque transmissions but can fail quickly due to the weakness inherent in its design. 

External Torx Plus low-profile head fasteners are engineered to provide optimal torque transfer and extended tool life, with a height similar to him or pan head fasteners. 


  • Hex Flange head or pan head bearing surface
  • 0° drive angle
  • Lobe engagement spreads forces over large areas to prevent stress risers and tool and fastener damage
  • Higher torque transfer capability than internal recesses
  • Drive system strength 5 to 6 times greater than the corresponding seating torque
  • Head height is similar to hex or pan head fasteners
  • Lower head volume (weight) than hex and pan head fasteners (18% and 41%, respectively)



  • Ensures optimal torque transmission and clamp load
  • Allows high torque transfer without damage to the fastener
  • Ideal drive system for applications that require high strength and torque capability in a low-profile head


  • Minimizes space required to accommodate head height
  • Excellent high-torque drive system for miniature fasteners
  • Reduced wear on drive tools for extended tool life
