Dimensions

When making a comparison of English wrenches we can see that there are models of different sizes, that is why we must first define what is the use that we are going to give the tool, since it depends on whether we choose a small or large wrench. that we can adapt to our needs.

Compact wrenches are suitable for working on small device repairs, as these usually have small nuts and bolts. Although they are very useful around the home, these mini tools can also be carried everywhere, making them practical for professional work at home. They generally have a length between approximately 20 and 25 cm and a maximum jaw width that can be between 2.4 and 3.3 cm.

Larger spanners are recommended above all for industrial use, in cases where the devices have large nuts and bolts, for this reason, it is common to find models from 25 to 80 cm in length. Those with the longest handle are used for leverage, facilitating adjustment in demanding professional jobs. In this sense, they can offer more than 8 cm of working width in the jaw.

Materials

Thus, certain models even have an angle of inclination in the head for greater practicality.

The head of the wrench can have the knurl or rotary knob on one side or in the center, this depends mostly on the user’s preference, since both systems are practical and smooth in most modern wrenches. In addition, some models include a hole at the end opposite the head that is used to hang the tool on the wall, allowing immediate access in the workshop.

Regarding the structure of the tool, it is advisable to buy a model that has been forged in a single piece, since this way it will be stronger and more durable, especially for frequent use in demanding jobs. In this sense, the weight of the wrench is essential to know if you can take it everywhere, so it is good to review this information in the technical details of the product.

Frequently asked questions

Q1: How to use a spanner?

The wrench is very easy to use, the first thing you should do is separate the fixed jaw from the mobile one, using the central or lateral wheel. The idea is that the distance between both jaws is greater than the size of the element you need to adjust. In this way, you just have to bring the tool closer and slowly bring the jaws together until a good adjustment of the nut or screw is achieved, so that you can loosen or tighten according to the need of the moment.

If it is a ratchet-type spanner, its adjustment is automatic, you just have to place the three support points around the nut and turn to the right to lock the tool and tighten. If you want to unscrew, then you have to change the direction of the tool and turn to the left.

Q2: What is the wrench made of?

The material par excellence used for the manufacture of wrenches is steel, this is because it is a very strong metal and it is not too heavy, however, some models are made of a chrome vanadium steel alloy, which It gives the product greater hardness and resistance to corrosion, in this way, the tool can offer a longer useful life.

Although some wrenches are forged from a single piece of metal, others have a handle made of fiberglass and polypropylene, two highly durable materials that nonetheless provide a more ergonomic grip when getting the job done.

Q3: How to remove rust from a spanner?

It is possible to restore a wrench that is rusted from the effects of moisture. First, you have to remove the oxide layer with a wire brush, brushing it over the entire surface with force. Later, you can use a drill with a metal polishing accessory, the idea is to visualize the good metal that is behind the damaged surface. Next, it is advisable to lubricate the adjustment mechanism of the jaws, so that it regains its smoothness, for this you can use multipurpose oil in spray or with a dropper.

Q4: Why does the wrench slip?

There are at least two ways of sliding the wrench. The most common is due to an incorrect adjustment when controlling the movable jaw to tighten the nut. This can occur due to lack of user experience, but also due to the slack that some keys have, in the latter case, you just have to turn the wheel a little more to put more pressure on the screw head and thus overcome the failure.

The other way of sliding has to do with the handle and the clamping, especially if the tool does not have a suitable handle. To avoid this, you can use gloves with an anti-slip surface on the palm of your hands, this is especially important if you are working in humid or oily environments.

Q5: Which is better, ratchet or conventional spanner?

We cannot say that one is better than the other. The conventional wrench allows a very precise adjustment and in fact incorporates a scale in millimeters for professional work. For its part, the ratchet spanner offers great practicality, since it automatically adjusts to the size and shape of the nut or bolt.

Q6: How to clean a wrench?

You can clean the wrench with ingredients that you have at home. To begin, you must place the tool in a container with white vinegar, trying to cover it completely. It is important that you let it work for a few minutes and then brush your teeth and remove any dirt or rust from the key. Afterwards, you can mix 1 cup of baking soda with 2 cups of water to submerge the faucet in this compound, allowing a few minutes to remove the remains of dirt. Finally, you just have to dry the tool and apply natural coconut oil or a multipurpose lubricant.

Q7: Who invented the wrench?

Although there is no consensus among historians, most think it was Edwin Beard Budding, an English engineer who lived between 1795 and 1846, however, the contributions of the Swedish Johan Petter Johansson in 1892 were also important.

Q8: What do the inches on a wrench mean?

In wrenches, inches refer to the length of the tool using the American standard measurement. Therefore, a 30-inch wrench is a tool that is 30 inches long.
