The Wera 840/1 ZBO 5mm Hex Pinned Security Bit is designed for substantial fastening applications where both high torque transmission and tamper-proof security are paramount. This 5mm variant is widely used in heavy machinery, industrial installations, and public infrastructure where larger security fasteners are specified to resist unauthorised interference. The tough viscous construction ensures this bit can withstand the rigorous demands of professional use, maintaining its performance characteristics even when working with hardened materials and under high stress. This bit showcases Wera's innovative Hex-Plus technology, which revolutionises the interface between bit and fastener by providing a greater contact surface in the head of the screw. This design substantially reduces the notching effect and more or less eliminates damage to the screw head, protecting your investment in quality security fasteners. The hexagon socket BO screw configuration, featuring a protruding pin in its drive profile, provides effective tamper resistance as standard hex tools cannot move these specialised fasteners. The universal 1/4" hexagon drive design (Wera connecting series 1) ensures compatibility with holders meeting DIN ISO 1173-D 6.3 standards and suits major power tool brands including Bosch, Fein, Holz-Her, Lecreux, and Metabo. Features and Benefits: • Hex-Plus technology for extended screw life • Ductile and tough for heavy-duty applications • Tamper-proof design prevents unauthorised access • 1/4" hexagon drive compatible with professional tools • Suitable for Bosch, Fein, Holz-Her, Lecreux, and Metabo Specifications: Bit Size: 5mm Length: 25mm Drive: 1/4" Hexagon Contents: • 840/1 Z Tamper-proof Hex-Plus BO bits, 5 x 25 mm
