Wera 05057662001 Pozidriv Insert Bit PZ.3

Product Description

The WERA 05057662001 is a PZ.3 Pozidriv screwdriver insert bit designed for use with 1/4 inch hex shank power tools, impact drivers, and bit holders. Machined from stainless steel, this bit delivers reliable torque transfer on PZ.3 fasteners without premature wear. At 2 inches overall length, it provides enough reach for recessed fastener applications while remaining compatible with standard bit holders and quick-change chucks. Electricians, HVAC technicians, plumbers, and general trade workers who regularly drive larger Pozidriv fasteners will find this a practical addition to their bit kit.

This insert bit is suited for residential and light commercial applications where PZ.3 Pozidriv fasteners are specified. It is commonly used in panel assembly, cabinetry, electrical enclosures, and mechanical equipment installation. The stainless steel construction makes it appropriate for environments where corrosion resistance matters, including damp utility rooms and outdoor-rated enclosures. It is sold individually and fits any standard 1/4 inch hex quick-change bit holder or drill driver.

Key Features

• PZ.3 Pozidriv tip profile for positive engagement on larger Pozidriv fasteners

• 1/4 inch hex shank fits standard quick-change holders and drill drivers
• 2 inch overall length provides reach for recessed or deep fastener locations

Compatibility

Designed as a standard 1/4 inch hex shank insert bit compatible with quick-change bit holders, drill drivers, and impact drivers that accept 1/4 inch hex tooling.

Installation Notes

Insert the bit fully into a 1/4 inch hex bit holder or quick-change chuck before applying torque. Confirm the bit tip seats completely into the Pozidriv fastener head before driving to prevent cam-out and tip damage. When used with an impact driver, select the appropriate torque setting for the fastener size and material to avoid overdriving. Inspect the bit tip for wear or deformation before each use and replace if the tip profile shows rounding.
