Hand wrenches are one of those everyday tools that you may ignore until you need them. You can often get a wrench near you to use in the project you are facing. But there are actually several different types of wrenches, and many of them are specially designed and used to do a specific job.

Wrenches are usually male or female. Male wrenches are inserted like a screwdriver head. Material wrenches have a socket that is placed on or around an object to be rotated. Both are used to loosen or tighten nuts, bolts, and even mechanical caps and bodies.

Wrenches come in a wide variety of styles and functions, some of which are mentioned here, although there are more wrenches that are very rare or specialized.

What is the classification or classes of wrenches?

A few common terms are used to classify wrenches for their subgroups. Knowing these terms will give you a better idea of ​​the purpose of using a wrench, but they all work with the broad term “wrench” (for example: Allen wrench vs. hex key).

What is the difference between a switch, a socket and a wrench?

The keys are usually very specialized and often appear as an old toothless key or as a T-shaped socket that may have a male or female tip. Allen wrenches, bottle openers and window hinges are all types of wrenches.

The socket wrench may refer to a unit or handle that attaches to cylindrical sockets. The socket is placed on the head and rotates vertically or horizontally, depending on the direction of the handle.

Wrench levers are tools used to turn the wrench head and have a design that has a pin or hook instead of the normal end. The term is mostly used in British English to describe wrenches in general, although it is used as a subset of wrenches in the United States.
