Hexalobular or 6-Lobe drive


Upgrade your product assembly by switching over to Hexalobular or Torx drive Screws.
The hexalobular socket screw drive, known as Torx or star drive, uses a star-shaped recess in the fastener with six rounded points.
It’s designed to permit increased torque transfer from the driver to the bit compared to other drive systems. Radial forces are drastically reduced resulting in longer tool life. It has vertical sidewalls which increases tool engagement.
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.

Advantages

Higher torque transfer

The driving forces are transferred through surfaces rather than through edges. This results in less wear and tear on tools and no damage to the surface treatment – the corrosion protection like plating or passivation is preserved.

Longer tool life

The optimal torque transmission extends the working life of screwdriving tools. This leads to considerable cost savings, above all when working with small screws or socket set screws. There is no «came out» effect typical with cross recess drive screws.

Large potential for rationalisation

One type of drive can be used for many different types of screw. This particularly applies to the size range up to M8. The product range used can be reduced. The logical result is less outlay on assembly tools and reduced storage and logistics costs.

Possibilities of slimmer heads

The high torque transmission opens up new possibilities for special shapes – a tool for different dimensions. Problems associated with installing low head or flat head screws are virtually eliminated.

Development of the SLIM – Ultra Low Profile screw is one such example.

Because of these advantages, Torx drive screws are very popular in the automotive and electronics industries.
