The Wera 840/1 ZBO 6mm Hex Pinned Security Bit is the largest variant in this professional range, engineered for the most demanding heavy-duty applications requiring maximum torque transmission combined with tamper-proof security. This 6mm size is essential for industrial machinery, heavy equipment assembly, and infrastructure installations where substantial security fasteners are specified to resist both high mechanical loads and unauthorised tampering. The tough viscous construction delivers exceptional durability and reliability for professional tradespeople working in the most challenging environments. Incorporating Wera's renowned Hex-Plus technology, this bit provides a significantly greater contact surface in the head of the screw compared to conventional hex tools. This advanced geometry reduces the notching effect to an absolute minimum and virtually eliminates damage to the screw head, ensuring your security fasteners maintain their integrity even after repeated installation and removal cycles. The hexagon socket BO screw design, with its characteristic protruding pin in the drive profile, delivers effective security as normal hex tools cannot engage these specialised fasteners. The industry-standard 1/4" hexagon drive (Wera connecting series 1) provides universal compatibility with holders conforming to DIN ISO 1173-D 6.3 and is suitable for major brands including Bosch, Fein, Holz-Her, Lecreux, and Metabo. Features and Benefits: • Hex-Plus technology maximises screw head protection • Tough viscous construction for extreme durability • Security pin design for tamper-proof applications • 1/4" hexagon drive for universal tool compatibility • Compatible with Bosch, Fein, Holz-Her, Lecreux, and Metabo systems Specifications: Bit Size: 6mm Length: 25mm Drive: 1/4" Hexagon Contents: • 840/1 Z Tamper-proof Hex-Plus BO bits, 6 x 25 mm
