How to use

Select the PZ 2 bit from the blister and insert it into a compatible 1/4" bit holder or screwdriver. Ensure the bit seats fully in the holder before applying torque.

After use, return bits to the blister to keep them organized and protected.

Recommendations

Use the bits primarily with Pozidriv fasteners and compatible 1/4" holders. Avoid using damaged bits on hardened or stripped screws. For power tools, reduce torque when starting and check bit condition regularly to ensure safe and reliable performance.
