The Wera 850/1Z PH Extra Tough Phillips Screwdriver Bits are a professional-grade bit solution designed for driving Phillips screws in hard materials and demanding applications. Built to Wera's "Extra Tough" standard, these bits are engineered for durability and reliable performance in materials that would quickly wear down standard screwdriver bits. The 1/4" hexagonal shank (Wera Connecting Series 1) conforms to DIN ISO 1173-D 6.3, making them compatible with all standard 1/4" bit holders, impact drivers, and screwgun chucks used across the trades. Ideal for carpenters, joiners, and general contractors working with dense or hardened materials, these bits are suited to both site work and workshop use.
