Screwdriver Bit PZ1 25 mm S2 in box, Tvardy (10 pcs pack)

Tvardy screwdriver bit PZ1, 25 mm length, manufactured from S2 tool steel and supplied as a 10-piece boxed pack. The bit is shaped for Pozidriv PZ1 screws and features a standard 1/4" hex shank compatible with hand drivers, magnetic bit holders and many power driver adapters. Its 25 mm working length balances access in confined assembly points with stable engagement for furniture assembly, carpentry and routine maintenance tasks.

Advantages

The S2 tool steel construction provides enhanced toughness and wear resistance compared with ordinary carbon bits, reducing deformation during repetitive use. A precisely formed Pozidriv tip ensures reliable fit into PZ1 fasteners, minimising cam-out and improving torque transfer. Supplied in a compact box with ten identical bits, the pack simplifies storage and replacement, making it practical for professionals and DIY users who require consistent performance and quick bit changes.

Suitable for

• Furniture assembly and flat-pack construction
• Carpentry work requiring Pozidriv PZ1 fasteners
• General maintenance and repair tasks
• Use with hand drivers, magnetic bit holders and compatible power tool adapters

How to use

Insert the 1/4" hex shank of the PZ1 bit into a compatible bit holder, hand driver, or power tool adapter. Align the Pozidriv tip with the PZ1 screw recess, engage firmly, and apply steady torque while keeping the driver axis straight to prevent slipping. For power tools, use controlled speed and moderate pressure to avoid over-torquing or stripping the screw head. Replace bits from the box as they wear to maintain reliable engagement.

Usage recommendations

Store bits in the original box to protect tips from damage and to keep sizes organised. For prolonged bit life, avoid excessive side load and use the appropriate torque settings on power drivers. Inspect tips periodically and replace any bit that shows rounding or significant wear to preserve screw heads and ensure efficient work.
