Wera 867/1 TORX® Bits, Z TORX 30 x 25 mm SB

On this page you will find the bit with article number WER05073316001. Below you can read what to look out for when choosing the right bit, so that your screws are fastened neatly and your bit and fastener are damaged as little as possible.

What does T30 mean for a torx bit?

The designation T30 refers to the size of the six-lobe star profile. A higher number means a larger profile, which suits larger screws and higher torque. The bit must fit the screw head exactly: if it is loose, the profile can strip and wear. Therefore always check the size stated on the screw or in the product information.

A bit of 25 mm: when is that useful?

The length of 25 mm is the common standard length for bits. It fits most bit holders and machines and is suitable for screws that are easy to reach. If you need to drive screws that sit deep in a recess or in a tube, a longer bit or an extension is often more practical. For normal screwing work, 25 mm is usually more than enough.

Who is this Z TORX bit intended for?

This bit is intended for those who regularly work with screws with a Z TORX drive, for example in assembly work, construction or renovation. Because the bit is supplied as a single pack, it is also handy as a spare or to replace a worn bit. Preferably use a bit in good condition: a worn bit gives less grip and increases the risk of damaged screw heads.

Tips for longer use

Press the bit firmly and straight into the screw head before you start turning, and keep the machine in line with the screw. On a screwdriving machine, do not set the torque or speed higher than necessary. Replace the bit as soon as the edges of the profile are rounded, as this prevents damage to your screws.

Frequently asked questions

Does this bit fit my cordless screwdriver?

Usually yes, if your machine has a standard bit holder with hexagon socket. Check your machine's socket if you are not sure.

What does SB mean in the product name?

SB stands for self-service and refers to the packaging in which the bit is offered, such as a card or blister.

Is a Z TORX bit the same as a regular torx bit?

They look similar, but always check that the profile and size of the bit match the screw head you want to use.
