Wera 868/1 Impaktor Square Robinson Screwdriver Bits

The Wera 868/1 Impaktor Square Robinson Screwdriver Bits are professional-grade bits engineered for square socket screws, delivering exceptional durability and performance with impact drivers. Featuring Wera's innovative Impaktor technology, these bits provide an above-average service life even under extreme working conditions, making them ideal for demanding applications on construction sites and workshop environments. The diamond-particle coating on the bit tip creates enhanced friction resistance, literally biting into the screw head to prevent cam-out and slipping during fastening operations. This rough coating ensures a secure fit in square socket screws, maintaining positive engagement even when working with worn or damaged fasteners. The ¼" hexagon drive conforms to DIN ISO 1173-F 6.3 standards and is compatible with Wera connecting series 4 holders. Particularly suitable for use with customary impact drivers, these bits are designed to withstand the high-torque, repetitive impacts typical of professional trade applications. Whether you're working with decking screws, coach bolts, or specialist square-drive fixings, the Impaktor range delivers the reliability and longevity that tradespeople require.
