About this product

This Wera 840/1 ZBO bit is supplied in a 6mm hex size with a 25mm length, the largest option in this range and designed for substantial hexagon socket BO security screws used in heavy engineering, structural frameworks, and large-scale industrial installations. The 6mm drive handles significant torque demands with authority, providing secure engagement where unauthorised tampering must be prevented. Wera's Hex-Plus technology increases the contact surface within the screw head to its maximum potential at this size, virtually eliminating the notching and rounding that causes costly fastener damage. The extra tough construction ensures long service life even under the most demanding conditions.
