POWERDRIV SOCKETS
®

Zebra Profile with Hex Drive.

The profile, which, as with
many other inventions is dervied from space
technology, the straight segments are replaced by
intermeshing radii.
The results:
• The force is applied over the entire surface,
not just along the edge.
• Better distribution of the applied force, but
also of the generated force.
• Lower loads on all components.
• Transitions from one flat to another are
rounded off, not sharp edged.
• Distribution of stresses without undesirable
notch effect (peak stress points in the
corners).

Zebra Profile with Square
Drive.

The Zebra square profile with
rounded edges reduces, similar to the hex drive,
the notch effect.
This means that sharp angles, which are prone
to form zones of high loads, no longer exist,
translating into a longer service life and higher
transmission of force.

Zebra Profile.
• Powerful action due to higher drive torque.
• Transmission of torque well above DIN
requirements.
• Longer service life of the drive as well as
screws.
• Less strain on surface-coated and soft metal
screws.
• Damage is avoided to a large extent.
Without Powerdriv - With Powerdriv - • Fewer cases of seizing of sockets or screw

surface. • Time savings.
• The ball guide groove is milled into all four
sides of the square hole.
• The socket can be pushed onto the drive in
any position.
