Long-lasting screwdriving with Wera bits

Practical benefits

Reduced wear via torsion: The built-in torsion zone absorbs peak torque loads so you prevent premature bit breakage during heavy screwdriving tasks.
Tough design for versatility: The tough viscous construction allows you to drive fasteners into hard materials without chipping or damaging the bit.
Secure fit in fasteners: The precision PH 2 profile with a standard 1/4" hex drive ensures you transfer maximum torque without slipping out.

In a nutshell

The right choise for

With the Wera 851/4 tz screwdriver bit, you drive Phillips ph 2 screws securely into hard materials such as metal and wood. The integrated torsion zone absorbs peak torque loads during heavy-duty screwdriving, preventing premature wear and bit breakage. Its tough viscous design provides an exact fit in fastener heads, significantly reducing the risk of cam-out. With an overall length of 50 mm, you easily reach recessed screws without needing an extra extension adapter. The standard 1/4" hexagon drive fits directly into bit holders and drill chucks, giving you full control and consistent performance.

Features and benefits

TZ-Bits are tough bits with a torsion zone. Torsion bits absorb the damaging peak torque loads in the torsion zone. This prevents premature wear and enhances the service life of the bits.
Tough Wera bits prevent the tip from breaking prematurely. Z-bits usually are the bit for universal screwdriving applications.
