Step 71External Torx-Plus® Low-Profile 5-Lobe
[[br]]Textron Fastening Systems is now Acumet Global Technologies and developed the External Torx-Plus® Low-Profile screw drive system.
The external hex drive allows high torque transmission, but can fail quickly due to weaknesses inherent in its design. External Torx-Plus® low-profile head drive system is engineered to provide optimal torque transfer and extended tool life, with a head height similar to hex or pan head fasteners. The drive utilizes a 0° angle. Lobe engagement spreads forces over large area to prevent stress risers that cause tool and fastener damage. Higher torque transfer capability than corresponding internal recesses. Drive system strength 5 to 6 times greater than normal seating torque. Excellent high-torque drive system for miniature fasteners
An external Torx® version exists, where the screw head has the shape of a Torx® screwdriver bit, and a special Torx® socket is used to drive it. These are found primarily on automobile engines. [[br]]
