TOBI DRIVE PROJECT

Due to the special geometry of the drive concept it was possible to combine features like axial alignment, maximum contact surface, self holding of the screw as well the optimization of the fatigue strength of the driver bits. All these supports e.g. working over head with one hand as well as the automated fastening process. Reduce tool wear, take advantage of versatility and test the system.


AXIALLY ALIGNED

During the insertion of the driver bit in the screw recess, the system will be axially aligned. This is e.g. an advantage for an automatic screw feed with robots and for critical applications where the screw- or nut thread musn’t be damaged. The converging surfaces ensure that the screws can’t drop out of the tobi driver bits until they are tightened. Especially for working with one hand on a ladder over head.


COMPABILITY WITH OTHER DRIVE TOOLS

Each TOBI screw head profile is compatible with a corresponding hexalobular socket or AW screwdriver bit of the same dimension in case of repair.


MAXIMUM CONTACT SURFACE

Because of the greater contact surface between the TOBI screw recess and the driver bit compared to other drive systems, the load for the driver bit will be reduced significantly. The new design increase the service life of the tools and thus makes a significant contribution to cost reduction.


TORQUE COMPARISON OF DRIVER BITS

The ultimate torque of the new concept is much higher due to the special geometry of the profile and the optimized stress distribution. Over the entire spectrum, the TOBI ultimate fracture torque is 30% up to 60% stronger.


Head hight reduction for the low profile of the TOBI screw head design. This is possible because of the system`s special drive contact surface between the recess and the driver bit.

ADVANTAGES OF THE DRIVE SYSTEM
