Experience the ultimate in fastening technology with these tough, viscous bits designed for hexagon socket screws, perfect for a variety of applications. Featuring the innovative Hex-Plus profile, these bits provide a greater contact surface within the screw head, significantly reducing the notching effect and minimizing the risk of damage to the screw head. This ensures a secure fit and enhances the longevity of both the bits and the screws.

Engineered for versatility, these bits are compatible with a ¼" hexagon drive, making them suitable for holders as per DIN ISO 1173-F 6.3. A standout feature of these bits is their design for hexagon socket BO screws, which incorporate a protruding pin in their drive profile.
