Screwdriver bit set Wera PZ 2 855/1 Z DIY, S2 tool steel, diameter 6.3 mm, 10 pcs

Wera PZ 2 855/1 Z DIY is a set of ten Pozidriv (PZ) screwdriver bits manufactured from S2 tool steel, featuring a 6.3 mm round shank. The bits are intended for use with bit holders, quick-change chucks and compatible cordless or manual drivers. Designed for general assembly, maintenance and repair work, the set delivers consistent fit to Pozidriv fasteners used in wood, metal and composite materials.

Advantages

The S2 tool steel construction provides increased hardness and wear resistance compared with standard tool steels, maintaining tip geometry under repeated use. The 6.3 mm diameter shank fits industry-standard bit holders and is suitable for high-torque applications with appropriate drivers. The set of ten identical PZ 2 bits offers quick replacement on the job and reduces downtime when multiple fasteners require the same drive type.

Suitable for

• Driving Pozidriv PZ2 screws in furniture assembly
• General maintenance and repair of machinery and appliances
• Woodworking tasks that use Pozidriv fasteners
• Installations involving metal sheet or composite panels with PZ fasteners

Key specifications

• Bit type: Pozidriv PZ 2
• Material: S2 tool steel
• Shank diameter: 6.3 mm (round)
• Quantity in set: 10 pieces
• Compatibility: Designed for standard 1/4" hex bit holders and quick-change chucks

How to use

Select a PZ 2 bit from the set and insert the 6.3 mm shank into a compatible bit holder or driver until it locks. Ensure the driver and bit are aligned with the screw head to prevent cam-out and tip damage. Use appropriate torque settings on cordless drivers to avoid overdriving; for delicate materials, use a manual screwdriver or lower torque. Replace worn bits promptly to maintain fastener engagement and prevent damage to screw heads.

Usage recommendations

Store bits in a dry, organized container to prevent corrosion and to keep tips protected. Match the PZ 2 bit size accurately to Pozidriv screw heads to ensure optimal contact and reduce the risk of stripping.
