It can be used with any thread style

SUPERIOR PERFORMANCE AND STRENGTH

The 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. 

Features

• 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)

Benefits

• 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
