Set di bit per cacciavite Wera Bit-Box 20 BTZ PH

The Wera Bit-Box 20 BTZ PH contains 20 Phillips (PH) screwdriver bits designed for common screwdriving tasks. Each bit has a 1/4" (6.35 mm) hex shank with a length of 25.4 mm and features an elastic BiTorsion zone that diverts kinetic energy under peak loads plus a softer BiTorsion tip zone to reduce tip twisting and extend service life. Bits are stored in a durable plastic Bit-Box with colour coding by profile and size and markings for easy toolfinder identification.

Advantages

The BiTorsion design reduces stress on the bit and screw by absorbing peak loads, which increases bit lifetime and lowers the risk of damage. Colour coding and size stamps enable quick selection. The 1/4" hex shank is compatible with standard holders to DIN ISO 1173‑D 6.3, and the compact Bit-Box provides organised storage and portability.

Suitable for

• Screwdriving with Phillips (PH) screws
• Use with 1/4" hex bit holders and drivers
• General maintenance, assembly and DIY tasks
• Professional trade work requiring reliable Phillips bits

How to use

Select the required Phillips bit from the Bit-Box using the colour coding and size stamp. Insert the 1/4" hex shank into a compatible bit holder, screwdriver, or drill with a 1/4" hex chuck. Apply steady pressure and drive screws with controlled torque; the BiTorsion zones will absorb peak loads to protect the tip and screw under higher stress.

Recommendations

For best results, use the correct Phillips size for the screw head (typically PH 2) and avoid excessive torque that exceeds the screw or tool rating. Store bits in the Bit-Box to keep them organised and protected from corrosion and damage.
