Screwdriver Bit Wera PZD Gr.1 L25mm zähhart C6.3 for Phillips/Pozidriv screws

Wera PZD Gr.1 L25mm zähhart C6.3 is a precision screwdriver bit engineered for Pozidriv (PZD) screw applications. With a 25 mm working length and manufactured from zähhart C6.3 steel, the bit is designed to deliver reliable engagement and extended wear resistance. The compact form factor makes it suitable for use in confined spaces while remaining compatible with standard 1/4" (6.3 mm) bit holders and screwdriver handles.

Advantages

The bit offers accurate Pozidriv profiling to reduce cam-out and ensure stable torque transfer. Its zähhart C6.3 steel construction balances hardness and toughness for improved service life under repeated use. The 25 mm length provides accessibility in tight assemblies without sacrificing control, and the standard diameter ensures broad compatibility with common bit holders and multi-bit screwdrivers.

Suitable for

• Assembly of furniture and fixtures using Pozidriv screws
• Maintenance and repair work requiring precise screw engagement
• Electronics and appliance servicing in confined spaces
• General DIY and professional trade tasks involving Pozidriv fasteners

Key specifications

• Drive type: Pozidriv (PZD) Grade 1
• Length: 25 mm working length
• Shank diameter: 6.3 mm (standard bit diameter)
• Material: zähhart C6.3 steel (hardened/toughened tool steel)

How to use

Insert the Wera PZD Gr.1 L25mm bit into a compatible 1/4" (6.3 mm) bit holder or screwdriver chuck until it seats securely. Align the Pozidriv bit tip with the screw head, apply steady axial pressure and turn with the appropriate torque for the screw size. For power drivers, use low speed and controlled feed to avoid stripping. After use, remove the bit and store it in a bit holder or box to protect the tip profile.

Usage recommendations

Use the bit with correctly sized Pozidriv screw heads and avoid excessive lateral force. Regularly inspect the tip for wear and replace when signs of rounding or deformation appear. For high-torque or impact applications, consider using bits specifically rated for those tools to preserve the zähhart C6.3 bit life.
