Wera Torsion Extra Hard Pozi Screwdriver Bits PZ3 50mm Pack of 1

The Wera 855/4 TH Torsion Extra Hard Pozi Screwdriver Bits are professional-grade PZ3 bits engineered to handle demanding fastening applications with reduced wear and extended service life. At the core of these bits is Wera's Torsion zone design, which diverts kinetic energy away from peak loads during use. This absorbs impact stress rather than concentrating it at the tip, significantly reducing the risk of premature wear and breakage — particularly valuable when working with semi-hard material
