T-handle hexagonal screwdriver for socket head screws. Hex-Plus offers a greater contact surface in the head of the screw. The notching effect is therefore reduced to a minimum and damage to the screw head more or less eliminated. The ideal handle shape makes the transfer of higher tightening and loosening torque possible. The ergonomic design of the handle fills the palm of the hand and the fingers rest in the soft, rounded recesses. The whole hand is in contact with the handle so there is no frictional loss between the hand and the handle.
