Reliable screwdriving power for heavy tasks
- Durable Wera torsion zone: The built-in torsion zone absorbs peak loads, so you prevent premature bit wear and breakage.
- Extra hard construction: Engineered with hardened steel, it ensures you drive Pozidriv screws into semi-hard materials with ease.
- Extended 50 mm reach: The longer profile allows you to access recessed fasteners in confined workspaces effortlessly.
With the Wera 855/4 th bit, you tackle Pozidriv fastening jobs with complete control and confidence. The built-in torsion zone cushions peak torque loads, effectively preventing premature bit wear and unexpected tip breakage. Its extra-hard steel design delivers a dependable grip on PZ2 screws in semi-hard materials, keeping cam-out to a minimum. The extended 50 mm length gives you the reach needed to access recessed screws in tight or hard-to-reach spaces effortlessly. Equipped with a standard 1/4" hexagon drive, this bit fits directly into your bit holder or drill driver for smooth, productive assembly work.
