Wera 840/1 ZBO Hex Pinned Security Bit Extra Tough

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.
