Wera 855/1 PZ BTH BiTorsion Extra Hard Pozi Screwdriver Bits PZ3 25mm Pack of 1

This variant is the PZ3 x 25mm Wera 855/1 BTH BiTorsion Extra Hard Pozi Bit, designed for larger Pozidriv screws typically found in heavy-duty joinery, structural timber work, and demanding site applications. The PZ3 profile ensures a secure, well-fitted engagement with larger fasteners, reducing cam-out and operator fatigue, while the 25mm length suits standard bit holders and power tools. The BiTorsion zone effectively dissipates kinetic energy during high-torque driving, considerably reducing the risk of bit failure and delivering a significantly longer service life. The extra-hard construction provides excellent resilience when working with semi-hard materials. Supplied as a single bit. Features and Benefits: • BiTorsion zone manages peak load energy to prevent premature breakage • Extra-hard design ensures lasting performance in semi-hard materials • 1/4" hexagon drive conforming to DIN ISO 1173-D 6.3 • Colour-coded for instant identification via Wera's 'Take it easy' tool finder
