Product details

Extremely durable Wera bits for hexagon socket screws, suitable for universal use. Hex-Plus provides larger contact surfaces in the screw head. This minimizes notching and nearly eliminates the destruction of the screw head. Internal hex BO screws have a protruding pin in their drive profile that prevents unauthorized loosening, as these screws cannot be operated with standard hex tools. 1/4" hex, compatible with holders according to DIN ISO 1173-D 6.3.
