Adjustable wrench

The adjustable wrench allows you to screw or unscrew bolts or hexagonal screws of different sizes. The undeniable advantage of the adjustable wrench is that the opening of its jaw can be adjusted by means of the wheel (worm screw) and it is therefore not necessary to change the tool every time the you encounter a nut or screw of a different size. This adaptable aperture is sometimes provided with a millimeter graduation.

The adjustable wrench therefore replaces several flat wrenches in the most common situations and can therefore prove extremely practical. On the other hand, the opening of the key is done at the front, this makes it easier to hold nuts/bolts in tight places.
