How to use a Ratchet Wrench

The Ratchet Wrench allows the user to tighten a bolt repeatedly without repositioning the tool at all times. An internal ratchet holds the socket in place while the wrench arm is repositioned. This makes the user's arms and hands less fatigued and reduces the risk of slipping and injuring themselves, as well as making work easier and faster. Once you experience the ease provided by the tool, you will hardly return to the old  common tools . But how to use a Ratchet Wrench?

Wear a pair of gloves to protect your hands when using the key. Take a socket that fits the bolt or nut you intend to handle. On the back of it there is a notch which is where the switch is engaged (the socket in the head of the switch fits snugly into the socket of the socket).
On the switch head body, shift the selector to the right to make sure it will turn clockwise. Position in the opposite direction if you need the wrench to unscrew counterclockwise.
Place the wrench with the socket already positioned on the bolt or nut to be tightened. Confirm that the socket is properly secured and fitted to the screw head or nut. Replace with a smaller socket if it is too wide for the screw, or with a larger one if the chosen socket does not fit.

Keep one hand on the Ratchet Wrench's head to steady it in position. With the other hand, twist the wrench slowly but firmly clockwise in a semicircle on the bolt or nut. Return the wrench arm and listen for the ratchet clicks by repositioning inside the wrench. Repeat the movement, twist and return to position after the semicircle. Continue with the process until the bolt or nut is tightened as desired.

Remove the Ratchet Wrench with the bolt or nut socket. Detach the socket from the wrench and return them to the toolbox .

Hex ratchet wrench, applications and features!

Have you ever used a ratchet wrench? If you have a key that changes the way you work, it's the ratchet key, it makes the work much easier. In this article the World of Electrics shows how it works and how to use a hex ratchet wrench.

hex ratchet wrench
The wrench with a ratchet system is one of the tools that makes the professional's life easier. There are several models of ratchet wrenches on the market, such as hexagonal, screwdriver, phillip, allen etc.

But the most used model is the hex ratchet wrench. The hex ratchet wrench is used for hex head screws and its mechanical system allows the wrench to turn only to one side, making it much easier to use for tightening or loosening hex screws.

When we use a common hex wrench, when tightening or loosening it is necessary to keep removing and placing the wrench to set the tightening position. With the ratchet wrench this is not necessary.

We will show two types of ratchet wrenches, the first is the standard ratchet wrench, with a chrome vanadium steel body, chrome finish, handle with special coating, reversible ratchet, quick release system and 45 teeth. Where it is possible to change the pipes for different sizes of screw heads.

And the second hex wrench is a kit of hex wrenches that all wrenches are ratchet and do not have a pipe exchange. It looks a lot like a common hex key, but with a ratchet, making it simpler.

How does the turnstile system work?
In both types of ratchet wrench there is a wrench or lock, which when changing the position of the lock, the ratchet changes its function to tighten or loosen the screw.

In the standard pipe ratchet wrench, just turn the wrench on the top written tighten, to lock the ratchet to one side or the other.

In the hex wrench kit with ratchet, just push the latch up or down, thus locking the ratchet to one side or the other.

The ratchet system is simpler than it looks, it consists of a gear that rotates in both directions and a lock that prevents the gear from turning depending on the position the lock is in, see the image below.

This system that locks the turning to one side, but allows turning to the other, is the great differential of ratchet keys.

To change the standard ratchet wrench pipes, just press the button on the top of the wrench and remove the pipe. There is a ball at the bottom that prevents the pipe from entering or leaving, and when you press the button, the ball allows the pipe to be removed and fitted.

This feature in English is called “quick release”, which means quick release, it is very important when you want to change the socket using only one hand.

Pneumatic ratchet wrench
Another type of ratchet wrench is pneumatic, pneumatic tools work by means of compressed air, generated by compressors that mechanically capture the air from the environment and increase its pressure, thus transforming the air into energy.

The use of pneumatic tools is more frequent in industries, but they can also be used in simple manual work. Pneumatic tools are used to replace human power in cases where continuous repetition of movement is required.

Decreasing the time to perform a task is always important and the ratchet system keys are a great investment to save time. Another tool that also helps to save time is the stripper pliers. In the video below the Mundo da Elétrica channel, we show how the stripper pliers work.
