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

Pozidriv is a cross-head system that at first glance looks like Phillips. However, they are two different systems. A Pozidriv bit fits best in a screw head of the same shape, so it is important to choose the right type of bit.

Pozidriv PZ 1: the size and how to recognise it

The designation PZ 1 indicates the size of the tip. You recognise a Pozidriv screw by the extra small ribs between the arms of the cross in the screw head. The bit has matching ridges there, so it grips better in the screw head. Choose the size that fits well in the screw head without play, because a bit that is too large or too small can damage the head.

Bits of 25 mm: for which use?

A length of 25 mm is the common standard length for bits used in a bit holder or drill and screwdriver machine. The bit is compact and fits most standard holders with a hex shank. If you have a screw that sits deeply countersunk or need to work in a hard-to-reach place, a longer bit or an extension may be more convenient.

Frequently asked questions

What is the difference between Pozidriv and Phillips?

Both are cross-head systems, but Pozidriv has extra small ribs between the arms of the cross. A Pozidriv bit therefore fits best in a Pozidriv screw.

Does this bit fit in my drill or screwdriver machine?

A bit of 25 mm fits in bit holders with a standard hex shank. Always check the holder or chuck of your own machine.

How do I know whether I need PZ 1?

The size depends on the screw head. Fit the bit into the screw: it should sit firmly and without play. If it is loose, try a different size.
