The Wera Bit-Box Bi-Torsion Extra Hard Pozi Screwdriver Bits are a pack of 20 PZ2 screwdriver bits engineered for professional use with Pozidriv screws, designed to withstand the demands of heavy daily use on site. At the heart of these bits is Wera's BiTorsion zone — a dedicated torsion area that absorbs and redirects kinetic energy during peak load events. This significantly reduces the risk of bit breakage and extends service life, making these bits particularly well-suited to applications where impact drivers or high-torque tools are in use. The extra hard construction makes these bits ideal for driving screws into semi-hard materials, where standard bits are prone to cam-out or premature wear. The 1/4" hexagon drive (Wera connecting series 1) conforms to DIN ISO 1173-D 6.3, ensuring broad compatibility with standard bit holders and power tool chucks. Identifying the correct bit on a busy site is straightforward thanks to Wera's Take it easy tool finder system, which uses colour coding by profile type and a size stamp on each bit. All 20 bits are stored in a practical Bit-Box designed for easy single-handed removal.
