Wera 840/4 Z Hex-Plus BO 6,0 x 89 mm

Extremely durable Wera bits for hexagon socket screws, suitable for universal use. Hex-Plus offers larger contact surfaces in the screw head. This minimizes the notch effect, nearly eliminating the destruction of the screw head. Hexagon socket BO screws feature a protruding pin in their drive profile. This prevents unauthorized loosening, as these screws cannot be operated with standard hexagon socket tools. 1/4" hexagon, compatible with holders according to DIN ISO 1173-F 6.3.
