For secure gripping and high transmission of force.
The POWERDRIV® system enables a high transmission of force at the wrench end and reduces wear on the bolt heads. POWERDRIV® does not grip bolt heads at the corner as is usually the case, rather it grips the sides. This enlarges the driving flat and permits a higher transmission of force. The service life of the screws is increased, as stripping of heads is prevented. Even old and rusty screws can be loosened virtually trouble-free with the POWERDRIV® without rounding off.
