Hexalobular socket according to ISO 10664
The notion of a drive with hexalobular sockets are a decisive step in developing drives better adapted to manual and automated assembly. This drive is becoming increasingly popular throughout the world.
Compared to drives like cross recesses and conventional hexagon sockets, this system is characterized by a lower risk of deterioration and a lower pressure force requirement. The typical «cam out» slipping of the tool has hence been eliminated and the force transmission improved.
The general dimensions are given in the product information of the respective catalogue group.
The Torx compatible drive is a reliable method of fixing screws. This drive can take more torque and does not slip.
The hexalobular socket screw drive, known as Torx or 6-Lobe or star drive, uses a star-shaped recess in the fastener with six rounded points.
It was designed to permit increased torque transfer from the driver to the bit compared to other drive systems. This system features a 15-degree drive angle which provides high torque transfer.
Radial forces are drastically reduced resulting in longer tool life.
It has vertical sidewalls which increases tool engagement CAMOUT is defined as the force upward on a screwdriver as the torsional force is increased to tighten the screw.
Torx Screws do not have camout problems as no camout forces are created to push the driver up and out of the fastener recess.
Due to this, the pressure required to keep the screwdriver in the socket reduces significantly and therefore reduces operator muscular stress and fatigue.
Because of these advantages, Torx drive screws are very popular in the automotive and electronics industries. This is also the preferred drive for our range of UltraSlim screws.
