Wera 867/1 TORX® Bits, Z TORX 20 x 25 mm SB

Z-TORX resembles the familiar six-lobe Torx profile, but is a variant of its own. It is therefore important to check beforehand which profile the screw you want to use has. A bit that fits the head well gives more grip and protects both the screw and the bit from wear.

Which screws is this bit intended for?

This bit is intended for screws with a Z-TORX profile in size 20. This profile is used in various applications in construction, industry and assembly. If you are unsure whether a screw is really Z-TORX, compare the bit carefully with the screw head or check the screw's specifications. A standard Torx bit of the same size is not automatically a suitable alternative.

What does a length of 25 mm mean?

The length of 25 mm is the common length for standard bits. Such a bit fits in most bit holders and machines with a hexagon drive. If the screw is difficult to reach, for example in a deep recess, a longer bit or an extension is sometimes more convenient. For regular screwdriving in easily accessible places, 25 mm is usually sufficient.

What should you pay attention to when screwing?

Place the bit straight and fully into the screw head before you start turning. This prevents the bit from slipping and damaging the profile. It is better to replace a worn bit in time, because the drive then grips less well. Also pay attention to a suitable torque and a suitable speed, especially with smaller screws.

What does SB mean in the product name?

The addition SB refers to the packaging of this article. On the product page you can see the price with and without VAT and the current stock status. If you need multiple bits or a different profile, see the Bits category for other sizes and versions.

Frequently asked questions

Does a standard Torx 20 bit also fit Z-TORX screws?

Not always. Z-TORX is a profile of its own, even though it resembles Torx. Preferably use the bit that matches the profile of the screw.

Can I use this bit in a cordless screwdriver?

Yes, as long as the machine has a bit holder or hexagon drive that accepts a standard bit of 25 mm.

How do I know if my bit is worn?

If the bit regularly slips in the screw head or the edges of the profile are visibly rounded, it is time for a new bit.
