Screwdriver Bit Wera Zyklop 8755 PZ 1 28 mm 1/4" drive

The Wera Zyklop 8755 PZ 1 28 mm screwdriver bit for 1/4" drive is a purpose-built accessory for working with Pozidriv PZ1 fasteners. At 28 mm length it fits standard 1/4" bit holders and ratchet adapters, providing accurate seating in Pozidriv screw heads and efficient torque transfer. The bit is intended for routine assembly, service and maintenance tasks where repeatable engagement and durability are required.

Advantages

The bit is manufactured to precise dimensional tolerances to ensure consistent Pozidriv engagement and reduce cam-out. Its 1/4" drive geometry guarantees compatibility with a wide range of bit holders and ratchets, enabling quick bit changes and secure fitting. Durable material and surface treatment improve wear resistance and extend service life under professional or DIY usage conditions.

Suitable for

• Assembly of furniture and fixtures using Pozidriv PZ1 screws
• Maintenance and repair of household appliances and electronics with PZ1 fasteners
• Professional trade work requiring precise Pozidriv screwdriving
• Use with 1/4" bit holders, quick-release chucks and ratchet adapters

Key specifications

• Tip type: Pozidriv (PZ1)
• Overall length: 28 mm
• Drive interface: 1/4" square drive
• Material: hardened tool steel with protective surface treatment
• Compatibility: standard 1/4" bit holders and ratchets

How to use

Insert the 1/4" square end of the bit into a compatible bit holder, quick-change adapter or ratchet. Align the Pozidriv tip with the screw head and apply steady axial pressure while turning to ensure positive engagement and reduce the risk of cam-out. For controlled torque, use an adjustable torque driver or a ratchet rather than excessive manual force. After use, store the bit in a holder or organizer to protect the tip geometry.

Usage recommendations

Choose this PZ1 28 mm bit when working with recessed or shallow Pozidriv heads where a short, robust bit helps maintain control. Inspect the tip regularly for wear and replace it when rounding or deformation is visible to avoid damage to screw heads. Use with appropriate socket adapters and follow torque guidance for the specific application.
