## Long description

Cross-head (Phillips) screwdriver bits PH2 from Wera, model 851/4 TZ SB SiS are two precision bits designed for routine assembly, maintenance and repair tasks. Made from alloyed tool steel with a SiS surface treatment and a toughened (F) tip, these bits combine wear resistance with reliable engagement in PH2 fasteners. The shank is sized F 6.3 mm, making the bits compatible with standard 1/4" bit holders and quick-change chucks. This 2-piece pack provides spare capacity for repeated use and reduces downtime during work.
Advantages
The alloyed tool steel core and SiS surface treatment provide enhanced abrasion resistance while the F toughened tip reduces the risk of tip deformation and cam-out under torque. Precision machining ensures accurate PH2 geometry for secure screw engagement and reduced slippage. The standard 6.3 mm shank guarantees broad compatibility with common bit holders, enabling fast bit changes and consistent performance across multiple fastening tools.
