What is the difference between a wrench and a screwdriver?

During work, there are often difficult situations where the use of a wrench alone is clearly inadequate. Then you have to take in the hands of special tools: they help in working with parts that have a thread. Among them are a screwdriver and a wrench. These technical devices serve for one purpose - to accelerate the work associated with the large number of used nuts, bolts and screws. At the same time, despite the similarity of the tasks being solved, a number of significant differences are observed among them. You can learn about this and which of the tools to use better from the review below.

What is a screwdriver

The screwdriver is an electrical tool whose main purpose is to work on screwing or unscrewing various screws, bolts and screws. One can only imagine how much time it will take to screw in several hundred screws by hand when assembling, for example, a regular built-in wardrobe for clothes or shelves for tools. With the use of this device all the work will take a few minutes. In addition, this power tool has some other additional features:

• use as a cordless drill;
• replacement with special tips of conventional hex keys;
• backlight function in low visibility conditions.

An electric screwdriver is also convenient because it can install screws to a predetermined depth. Therefore, all the heads of the screws will be located in the same plane, which will give the work a beautiful and complete look.

A few words about the wrench

Industrial or homemade wrench serves for installing and removing bolts and nuts. Some may accidentally confuse it with a drill, but experienced craftsmen will immediately point to a special nozzle in a holder that a conventional drill does not have.It will definitely not be able to do without it if you need to unscrew the old nut, which is so rusty that you simply cannot unscrew it with your hands or a key. The tool is issued in the following execution:

• pneumatic;
• petrol;
• hydraulic;
• running on electricity.

The wrench is widely used in repair shops and various assembly work. More powerful tools are used in mechanical engineering.

What is the difference of tools

Wrench is considered to be a tool. for professionalswhile the screwdriver is mainly used for smaller household jobs. The main differences between the wrench and the screwdriver are their following characteristics.

1. Wrench compared to the screwdriver more cumbersome and does not have a cartridge. He is at the end special rodon which the nut head fastens.
2. Wrench powerattached to the object, many times greater than the force of the screwdriver. With the first you can solve any "problems".
3. Significant weight and size difference of these mechanisms. Wrenches are usually bigger and heavier.
4. Screwdrivers have several modes of operationwhich can be adjusted.In contrast, no other special tools have this capability.

Thus, wrenches are used more often for heavy mechanical work, while its competitor is more often used for more simple household repairs. In addition, for simple tasks, you can try to make the wrench yourself using ordinary nozzles.

Which tool is better to choose? The answer to this question will depend on the type of work where these tools are needed. Considering the fact that a wrench has a tangential impact when working, it cannot be used to tighten the screws, as it will simply tear off the caps to them. However, if you ensure that there is no stop, he can make such a mount, which cannot be created even by the most powerful screwdriver. If small amount of work, which includes only the screwing of the screws, then this is enough for the usual screwdriver. Therefore, to decide what to choose for work - a screwdriver or a wrench, it is necessary, based on specific circumstances.

Is it possible to make a wrench from a screwdriver?

Of course, you can, with only one important caveat: it is unlikely that you will be able to get the same power that a tool made in an industrial environment has. But, very often too much power is needed. For example, if change tires on the car. Many people know how long the process of twisting the nuts from the wheels is. Of course, there is an opportunity to turn to specialists, but it will cost money. If you have a screwdriver on hand, you can quickly convert it into a wrench: this requires only an adapter with a head of a certain size, which must completely match the size of the cylinder wrench. It remains to secure this adapter in the cartridge and install the head. Wrench screwdriver is completely ready.

Of course, this will not be a complete tool, since it will still be necessary to loosen the nuts manually, but the time spent on all the wheels will be only one minute.
