Wera 851/1Z PH Extra Tough Phillips Screwdriver Bit

This Wera 851/1Z bit is sized PH3 with a 32mm length, purpose-built for driving larger Phillips screws found in heavy-duty construction, structural timber work, and industrial assembly applications. The PH3 tip provides the robust engagement needed for bigger fasteners, where cam-out and slippage can be a real concern. The extra tough construction delivers the strength needed to cope with high-torque demands, resisting deformation and extending bit life even in the hardest materials. Featuring a 1/4" hexagonal shank conforming to DIN ISO 1173-D 6.3, it fits securely in all compatible bit holders and power drivers. Features and Benefits: • PH3 tip suited to larger Phillips fasteners used in heavy-duty applications • Extra tough construction withstands high-torque and hard material use • Durable tip geometry reduces cam-out on large-headed screws • 1/4" hex shank compatible with all DIN ISO 1173-D 6.3 compliant holding tools • Reliable performance for structural and industrial fastening
