Screwdriver Bit Set Wera Bit-Box 20 BTZ PZ

The Wera Bit-Box 20 BTZ PZ contains 20 screwdriver bits designed for Pozidriv (PZ) screws and stored in a durable plastic bit box. Bits feature an elastic BiTorsion torsion zone that diverts kinetic energy under peak loads and a softer BiTorsion tip zone that prevents the bit tip from twisting, which prolongs service life. Bits are extra hard, have a 1/4" hex shank and are compatible with holders according to DIN ISO 1173-D 6.3. The Take it easy toolfinder provides colour coding by profile and size stamp for quick selection.

Advantages

Elastic BiTorsion zones absorb peak loads and reduce stress on the bit; a softer tip zone prevents twisting at the tip and extends bit lifetime. Extra hard material improves wear resistance. The 1/4" hex shank ensures secure engagement in compatible holders, and the colour-coded Take it easy system speeds up bit selection. The plastic Bit-Box keeps the 20 bits organized and transportable.

Suitable for (tasks / use cases)

• Driving Pozidriv screws (PZ) in wood, metal and composite materials

How to use

Select the required Pozidriv bit using the colour code and size stamp on the bit. Insert the 1/4" hex shank into a compatible screwdriver, bit holder or impact driver. Apply steady pressure and operate the driver at an appropriate speed for the screw and material. The BiTorsion zones will flex under peak load to protect the bit tip; if high resistance is encountered, reduce torque or use a manual driver to avoid damage to fasteners or workpiece.

Usage recommendations

Store bits in the Bit-Box to protect tips and maintain the colour coding. Use bits suited to the screw size (e.g., PZ2 for PZ2 screws) to avoid cam‑out. Replace excessively worn bits to maintain driving performance and safety.
