The Wera Bit-Box Pozi Impaktor Screwdriver Bits are a set of 15 PZ2 x 25mm impact-rated screwdriver bits, designed for use with impact drivers and supplied in a convenient reusable Bit-Box. Built around Wera's Impaktor technology, these bits are engineered to withstand the high-torque, high-frequency demands of impact drivers — delivering above-average service life even under the most demanding site conditions. This makes them an ideal choice for carpenters, joiners, and general contractors who rely on impact drivers throughout the working day. Each bit features a diamond-particle coating on the tip, which creates enhanced friction resistance and literally bites into the Pozidriv screw head to prevent cam-out. This secure engagement reduces screw and bit damage, helping tradespeople work faster and more accurately. The 1/4" hexagon drive conforms to DIN ISO 1173-D 6.3, ensuring compatibility with standard impact driver chucks and bit holders. The Bit-Box format keeps all 15 bits organised and easy to access on site, while Wera's Take it Easy tool finder system uses colour coding and size stamps so you can identify the correct bit at a glance.
