Wera 855/1 PZ Impaktor Pozi Screwdriver Bits

The Wera 855/4 PZ Impaktor Bit in PZ3 x 50mm is supplied in a pack of 5, combining a large PZ3 tip with a 50mm length to tackle heavy-duty fastening tasks that demand both size and reach. Ideal for structural timber work, large-format decking screws, and applications in confined or deep spaces. Built on Wera's Impaktor technology platform, this bit is designed to absorb and withstand the high-impact forces produced by impact drivers, greatly extending working life versus standard bits. The rough diamond-particle coating on the tip grips the screw head firmly, ensuring positive engagement and eliminating cam-out even at high torque.
