Customised drive combinations.


Combined drive concepts

FLEXIDRIVE® is a 2-in-1 solution, to reduce assembly costs and simplify maintenance.

The TORX® or hexalobular drive is an ideal option for cost-effective initial assembly. However, in order to simplify repairs and maintenance and to counter arguments regarding poor tool availability, FLEXIDRIVE® allows you to combine different drive types.

Method / principle

The efficient hexalobular drive is used for assembly. But for maintenance purposes a number of different tool options can be used. If the hexalobular drive becomes clogged with dirt, for example, or the right bit is not available, then there are other options such as an external drive for unfastening the threaded connection.


Greater flexibility for all areas of application. FLEXIDRIVE® is particularly suitable for products which are fastened by means of automated systems but which have to be released quickly and without special tools for maintenance purposes. That is why this drive combination is widely used in construction, agriculture, machine building and many other sectors.

Product benefits
  • Shorter assembly time through the use of hexalobular drives
  • Use of standard tools for maintenance and repair work
  • Fewer tools required
  • Longer tool life
