A key is one of the most necessary and important tools you need in a normal day. It is available in a male and female version, with a nut or bolt in the head, and in a female version, which comes with an attachment foot.

They are both skilled in tightening and loosening bolts and nuts.

Types of keys

Keys are also included in the classes according to their design.

Categories include:

  • Keys – These are designed for specialised use and often look like sockets. The nests are either T-shaped with male or female tips, or key-shaped without teeth. These include window handles, Allen wrenches and bottle openers.
  • Keys – These keys have hooks, some have pins other than the standard end. They are often used to turn keys.
  • The socket wrench is a wrench with cylindrical caps to which the handles are attached. The orientation of the handle allows the key to be turned horizontally or vertically after it is mounted on the product head.

Key type

1. Adjustable key

This is one of the most popular keys, also known as the sickle key. The key has an open end, while the other end mainly serves as a handle. The free end is equipped with a spiral screw, installed to open and close the sickle by turning in any direction.

Adjustable wrench

It is much thicker and therefore needs much more space to work. The advantage of this key is that you can use it optimally in most situations, because it is suitable for other keys such as socket spanners and ring spanners. This is advantageous for homework, for example with leaking pipes or taps.

2. Fork wrench

It is difficult to miss this wrench in a toolbox because it is widely used. The key comes with two U-shaped ends. The ends are of different sizes, with one end more visible than the other.

Impact wrenches

Useful for tightening or loosening nuts and bolts that are difficult to access due to their narrow shape. You can mount it horizontally or vertically on the target nut or screw, but the disadvantage is that the edges of the nut must be round.

3. Socket wrench

It is one of the best wrenches that can be used to tighten or loosen nuts and bolts. It’s easy to use because it has a built-in ratchet mechanism that allows you to tighten or loosen bolts and nuts without lifting a wrench. The open-end wrench is available in different drive sizes, including 1, ½, 3/8 and ¼.

The socket spanner can be used to attach the socket spanner to the drive and then rotate to secure or unlock it. The advantage is that it is possible to turn the key with short strokes and that in any case there is an obstacle on the road; this makes it possible to turn the key. You can use it for household repairs, such as tightening nuts and bolts in the toilet.

4. Ratchet wrench

This key is unique in its design. It gives you a handle that can rotate up to 360 degrees, with a long handle to give you the right leverage when you’re working. This has the advantage that the direction can be reversed with the handle while the other end tightens or loosens the fasteners.

Ratchet key

This wrench is effective for removing bolts and nuts that may be rusty and difficult to remove. He doesn’t slip because he has a bus attached to the bolt or nut. They are useful when you work in a car or when space is limited and you need to get the job done quickly.

5. Socket wrench

The pipe wrench is mainly used for fixing pipes that do not have flat sides. It is therefore preferable for plumbing because it has jaws that are serrated. This notch makes it possible to better connect the key to metal and PVC pipes, thus increasing efficiency.

Pipe Pliers

The design and construction of this wrench is not suitable for fasteners, but it is useful for sanitary and industrial installations. A wrench can damage fasteners and tools. Therefore, fasteners with a flat side should be avoided as much as possible.

6. KEY

The key comes with a C-shaped curved end on one side and serves as a handle on the other side. The C-bend is equipped with pins that can be used on various elements, including washers and screws.

The wrench is useful for providing a mechanical grip when applying a torque to turn an object.

7. Torque wrench

This key uses a manual or, in other cases, electronic mechanism to transmit the correct torque. It is used to tighten and loosen screws and nuts. It also enables accurate measurements and adjustments, especially in situations where accuracy is essential.

With this key you can maintain your vehicles in difficult conditions. You can also use the torque for industrial work, such as repairing the water mains. This key can also be used to repair bicycles and other equipment used in agriculture.

8. Key with bit

The point wrench has large handles with four nuts in four different directions. This X-shaped tip is also known as a wrench and comes with an extended length to create more pressure when tightening or loosening the nuts.

The wrench is also available in an L-shape with an open-end wrench on one side.
This wrench is mainly used in cars to tighten the wheel nuts, hence the name wheel support.

9 Allen wrench

The Allen wrench is hexagonal in shape. It is a metal part in the shape of an L or T with one of the legs as a handle. Due to the design of the wrench, the screw heads and hexagon bolts can be placed in the recesses.

Allen key

This key is generally available in SAE or metric sizes. This key can be used effectively when repairing furniture, bicycles and in other cases – to break the lock.

10. Knurled wrench
