Wera 855/1 PZ 31 Piece Impaktor Pozi Screwdriver Bit Set

The Wera 855/1 PZ 31 Piece Impaktor Pozi Screwdriver Bit Set is a professional-grade bit set designed for use with impact drivers, delivering exceptional durability and cam-out resistance for Pozidriv screws.

Each bit features Wera's Impaktor technology, engineered to withstand the extreme impulse peaks generated by impact drivers. The rough diamond-particle coating on the bit tip bites into the screw head, significantly enhancing friction resistance and preventing slipping — a common cause of bit and screw head damage on fast-paced sites.

The included Wera 897/4IMP R Impaktor holder adds further functionality, with a double-torsion spring that absorbs shock and a retaining ring magnet that holds screws securely in position. This makes it particularly well suited to overhead work and situations where rapid, single-handed screw positioning is essential. The magnet can be moved out of the screwdriving zone when working with metal, offering added versatility.

The set contains 30 bits across three Pozidriv sizes — ten each of PZ1, PZ2, and PZ3 — making it a practical everyday choice for carpenters, joiners, and general contractors working with a range of screw sizes. All bits use a 1/4" hexagon drive compatible with DIN ISO 1173-D 6.3 holders, and the holder itself accepts any standard 1/4" hex bit.
