Wera Hexagon Plus BO Screwdriver Bit, 4 mm Tip, 89 mm Overall

Tough viscous Wera bits for hexagon socket screws for universal use. The Hex-Plus profile 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. 1/4" hexagon, suitable for holders as per DIN ISO 1173-F 6.3. Hexagon socket BO screws have a protruding pin in their drive profile. This prevents any unauthorised loosening since the "normal" hex tools cannot move these screws. 1/4" hexagon, suitable for holders as per DIN ISO 1173-F 6.3.
