T-handle screwdriver: The ideal handle shape allows for the transfer of particularly high tightening and loosening torques. The ergonomic design of the handle fits well in the palm of the hand, and the fingers rest securely in the softly rounded grip recesses. The entire hand makes contact with the handle, minimizing friction losses between hand and handle. It features a holding function for securely holding the internal hex screw on the tool. Special surface treatment provides high corrosion protection and optimal fit in the screw.
