How does the self-setting jaw work?

You press the wrench onto the hex bolt or nut and the parallel jaws close to its size automatically. A lever mechanism then clamps the fastener between the jaws.

What sizes does it cover?

Wera says the adjustable Joker 6004 covers all metric and imperial dimensions in its field of application. The XXL version is the largest in the line.

Does it work as a ratchet?

Yes. The mechanical ratchet lets you turn the fastener without lifting the wrench off, and the corner-width prisms give a 30° return angle.

Is the XXL version worth it over the smaller Joker 6004?

Choose the XXL if you work on larger fasteners and need the extra reach and leverage. For everyday small fasteners the smaller versions are lighter and easier to handle.

Will it round off bolts?

The clamping lever is designed to grip the flats and reduce slipping and damage. On already rounded or corroded nuts it grips less reliably, so use a proper extractor there.

Can it replace a full spanner set?

It replaces several fixed spanner sizes in its range, which is its main appeal. It does not cover every size, and a torque wrench is still needed for specified torque values.
