Nut wrench.. The machines we use every day and how they work

Nut wrench:

Bolts and nuts are used a lot to connect things.

to each other. In order for this connection to be completed, they must be twisted and tightened tightly and precisely, which is beyond your fingers alone. In order to be able to perform this work completely, you need to use a nut wrench. The type that you see a picture of to the left of this statement is called the open-ended wrench, and it is the type most used by mechanics. This wrench is a useful tool, although it has one drawback, which is that it only fits a certain size of nails or nuts.

If you want a wrench that fits multiple sizes, you must use a different type of wrench, which is the English wrench, whose picture you see to the left of this statement.

In order to adjust this wrench to fit a specific nut or a special screw, you must turn a round screw next to the wrench handle, and this movement causes the screw to move forward or backward. This screw is connected to a piece of the wrench called the jaw. When the screw moves, the wrench moves with it in size, which results in the opening of the wrench changing so that it can accommodate different sizes of screws and nuts.
