This Wera 840/1 ZBO bit is supplied in a 5mm hex size with a 25mm length, making it an excellent choice for larger hexagon socket BO security screws found in heavy-duty machinery, structural assemblies, and industrial equipment. The larger 5mm drive transmits greater torque, making it particularly effective when dealing with tight or seized tamper-proof fasteners. The Hex-Plus profile ensures maximum contact between the bit tip and the screw recess, minimising wear and preventing the frustrating rounding that can plague lesser bits. Extra tough construction means this bit stands up to repeated hard-material use without compromise.
