Product Overview
The Wera 855/4 TZ PZ 2 (05060010001) is a Pozidriv bit from Wera's 855/4 TZ family with a torsion zone. The product is specified as a PZ 2 variant with a blade length of 50 mm and a 1/4" hexagon drive (Wera connecting series 4). The manufacturer's description highlights the torsion zone as a design feature.Function and Design
The bit features an integrated torsion zone (TZ), which, according to the manufacturer, dissipates kinetic energy from peak torques into the torsion zone. This is stated as a means to reduce premature wear and extend the bit's lifespan. The family is described as "tough" for hard materials and suitable for universal screwdriving applications. The 1/4" hexagon drive makes the bit compatible with Wera connecting series 4 and with holders according to DIN ISO 1173-F 6.3, as mentioned in the manufacturer's material.- Pozidriv (PZ) profile: PZ 2 (as specified for part number 05060010001)
- Torsion zone (TZ) for reduced peak torque impact
- 1/4" hexagon drive (Wera connecting series 4)
- Blade length: 50 mm (specified for this variant)
- Described as "tough" for use in hard materials
Typical Applications
In the manufacturer's documentation, the bit is described as suitable for universal screwdriving applications with Pozidriv screws. The 855/4 TZ family is specifically indicated for general use with Pozidriv screws, where the torsion zone is intended to limit wear during peak torques.Documentation
