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 notch effects and nearly eliminates damage to the screw head. Internal hexagon BO screws have a protruding pin in their drive profile. This prevents unauthorized loosening, as these screws cannot be operated with standard hexagon tools. 1/4" hexagon, compatible with holders according to DIN ISO 1173-D 6.3.
