Efficient assembly with hexalobular / Torx® drives
Torx (English Torque) is the brand name for a screw-drive profile in multi-circular shape. It is handled as a further development of the crossed slot and hexagon socket drive.
Inventor and patent holder was the Camcar Company. The Torx patent expired in the early 90s but the name is protected anyway. This is why the term Hexalobular is often used.
The special profile that looks like a six-pointed star with rounded tips and corners is corresponding a waveform and eliminates the weaknesses of the other drives.

The mounting forces are not by edges but transmitted by driving surfaces.
The size of the driving surfaces ensures the optimum power transmission. Very high torques can be also transmitted without damaging the head.
The corrosion protection is maintained.
Reduced tooling costs
The wave profile facilitates the touchdown of the tool.
The driving forces are perpendicular.
There are no reverse thrust forces (cam out-effect).
The life of the assembly tools increase thereby significantly.
The screw head is compared to other actuators smaller and requires less material.
Despite of small footprint can be transferred a higher torque.
Large standardization potential
One drive system can be used for many different screws. This reduces the expenses for tools, stock and logistics costs. Screws with low or flat heads can be mounted easily.
Hexalobular / Torx ® drive systems are now used by default in the automotive industry, machinery, electronics and many other industries worldwide.
In standard toolboxes are Hexalobular / Torx ® bits commercially available.
