Wera 855/1 TH SB Bits Pozidriv, PZ 2 x 25 mm

When driving screws, the combination of bit and screw head determines how well the torque is transferred. With the right bit, the screw head stays intact and the tool is less likely to slip.

What does PZ 2 mean on a Pozidriv bit?

Pozidriv is a cross-head shape with extra small ridges between the four arms of the cross. The sizes range from PZ 0 up to and including PZ 4, where a higher number means a larger tip. PZ 2 is a commonly used medium size for general screws in wood and sheet material. Check the screw packaging to see which size is needed.

Pozidriv or Phillips: not the same

A Pozidriv screw and a Phillips screw look similar, but the profiles are different. A Phillips bit in a Pozidriv head fits more loosely and the risk of cam-out is greater. If you recognise Pozidriv screws by the small lines in the head, use a Pozidriv bit as well.

Choosing a 25 mm bit

A 25 mm bit is the common standard length. It fits most bit holders and works well for screws in normally accessible places. If you need to drive screws into a deep recess or between components, a longer bit or an extension is more convenient.

Frequently asked questions

Does this bit fit in a cordless screwdriver?

The bit has a standard hexagonal shank and therefore fits most bit holders and cordless screwdrivers. Do check the chuck of your machine.

Can I use a Phillips bit for Pozidriv screws?

In an emergency it is possible, but the fit is poorer. The risk of slipping and damaged screw heads increases, so preferably use a Pozidriv bit.

How do I recognise a Pozidriv screw?

Look at the head of the screw. A Pozidriv head has four extra small ridges between the arms, next to the cross.
