It is made of chromed steel and the opening is adjustable up to a maximum of 26 millimeters, which makes it quite versatile as it allows you to work with bolts and nuts of various sizes.

Value for money: The cost is affordable and perfectly proportionate to the overall quality of the tool, both in terms of materials and finishes; it is ideal for home use.

Convenient to use: Unlike cheaper and spartan wrenches, this one has a non-slip PVC coated handle, so it offers a good level of comfort and a secure grip.

8. Amerbm Adjustable Gland Nut Wrench

The last product on our list is also a model intended primarily for home use and has many points in common with the Mannesmann key discussed earlier. This too, in fact, is made of chrome-vanadium steel, is equipped with a graduated scale for the precision adjustment of the opening of the jaws and has a handle covered in bi-material, to increase grip and comfort of use. .

But the Feimuosi wrench, in addition, is equipped with two hexagonal holes in the neck, 9 and 10 mm respectively, and a 19 mm plum mouth graft at the end of the handle.

  • 7463 Function 🛠️ : Fits hydraulic cylinders on agricultural loaders, compact tractor loaders, skid...
  • 1266 Function 🛠️ : Fits hydraulic cylinders on most farm and construction equipment; Offers...

Despite these characteristics, however, the finishes and assembly are decidedly coarse; moreover, the irregular fusion of the tool also makes the multifunctionality promised by the additional clamping holes useless. Overall, therefore, it is a decent key in terms of solidity, but far from offering the yield it promises, even if only for home use.


Comfort of use: The handle covered in bi-material is one of its main advantages, as it guarantees a good degree of comfort as regards the grip and application of force.

Sizes: The Feimuosi wrench is available in different sizes according to needs; in this case the sizes are four, respectively 6, 8, 10 and 12 inches in length.

Versatile: The structure is made to have additional holes for tightening different types of nuts and bolts. This key potentially also offers a fair degree of versatility.


Coarse finishes and assembly: Unfortunately, the additional clamping features are not always usable, due to the fairly coarse assembly and finishes.

How to choose the best wrenches

To understand how to choose a good wrench you must first of all know the characteristics that differentiate the different models in use and the average price of the tool based on its quality, so let’s try to clarify the subject.

Materials of manufacture and prices

The wrench, together with the hammer and the pliers, is one of the fundamental manual tools for maintenance and repairs, in fact it is an integral part of most of the toolboxes that are on the market.

It is usually made of chrome vanadium steel, in order to offer maximum strength and wear resistance, but the level of finishes and the overall quality of the tool can vary substantially depending on the price. The latter ranges from a minimum of 5 or 6 euros for the cheapest models up to 50 euros and more, depending on the specific type and, of course, the quality of the materials and finishes.

It is needless to underline, in fact, that low-cost wrenches are characterized by an equally low quality; they are essential, roughly finished, do not have the anti-slip coating on the handle that makes the grip firmer and improves comfort of use, and are usually much more prone to rusting, especially in the areas where the adjustment mechanisms are located .

If you have professional needs, therefore, it is good to absolutely avoid buying a low cost product just to save money; the same is true for those who have hobby-type needs of use, even if in a less rigid way.

For home and occasional use, on the other hand, you can also choose a low-cost product, being careful to choose one that offers a minimum of reliability more than the average.

The different types of adjustable keys

Furthermore, before deciding which wrench to buy, it is good to make an excursus on the different types available on the market and on their intended use, in order to choose the one that best suits your needs.

The wrenches can be divided into two broad categories, the fixed ones and the adjustable ones: so let’s begin to examine the different models that fall into the second starting from one of the most common: the so-called roller wrench.

This particular model has the front end similar to that possessed by a hexagonal key, with the difference, however, that one of the jaws is mobile and allows you to adjust the opening of the jaw by means of a helical roller.

The best models are those that have a graduated scale on the jaw and a notch on the movable jaw, as they allow you to adjust the opening more precisely than keys that do not have them. This type is mainly used to loosen and tighten bolts, and being able to adjust the opening allows you to act on a wide range of head bolts of different sizes.

The parrot wrench, on the other hand, is mainly used for plumbing work, as it is structured in such a way as to be able to adapt to pipes of different diameters. Also in the field of hydraulics, flat head wrenches are in great demand; the latter, in fact, are increasingly difficult to find now and, unlike the parrot ones, they offer the advantage of being able to work easily even in the tightest spaces.

The hex keys and the combination

Fixed wrenches are usually sold in sets consisting of a number of pieces that can vary from a minimum of 8 or 12 units up to 100 and more, depending on the case, but can also be purchased individually.

This category mainly includes hexagonal, ratchet and socket wrenches, but you can also find combined wrenches, that is, those that have a double hexagonal / hexagonal or hexagonal / ratchet end. Their application is more specific and they are usually used mainly in general mechanical workshops, where they are used for disassembly and assembly, as well as in specific ones for the repair of cars and motorcycles.

The socket wrench, on the other hand, is a variant of the ratchet one; it is usually sold in a kit that includes the key itself and its interchangeable bushes, which are metal cylinders of different diameters made to fit the bolt heads. Also in this case it is a tool used above all in mechanical workshops.

Furthermore, as regards this particular type of keys, prices are slightly higher and range from 10-12 euros for low-cost sets up to 200 euros and more for those intended for professional use.

Frequent questions

Who invented the wrench?

The first wrench was developed and patented in America by Solymon Merryck, in 1835, of whom very little is actually known, except that he was a boxer and who was the first American boxing champion of black ethnicity. Merryck became an inventor after retiring from the ring and, in addition to the wrench, he is also credited with inventing the ratchet.

According to some, however, and precisely due to the scarcity of biographical information on the life of Solymon Merryck, the real origin of the key is not certain. Some attribute the authorship of this invention to the English Edwin Beard Budding, who would have developed it in 1842.

Whatever the truth, when the first wrenches began to circulate, people were greatly amazed by the invention; consequently other inventors developed further variations of the key.

In 1858, for example, the Monkey key was developed whose name, by assonance, is due precisely to that of its inventor: Charles Moncky. In 1870, however, the American inventor Daniel Chapman Stillson patented another variant of the wrench: the adjustable tube wrench as we still know it today.

From these first examples, then, all the subsequent variants used today have been derived, which have been developed according to the type of processing required.

Why is it called a wrench?

The only country in the world where this particular tool is called a “wrench”, in reality, is Italy; in England, in fact, it is known as a spanner, while in the USA it is known as a wrench.

The specific reason why in Italy it is called proper wrench is still a matter of discussion; one of the theories, the same that indicates Edwin Beard Budding as the first inventor of this tool, attributes its definition to the fact that he was indeed English.

Another theory, on the other hand, reports that in Italy a very similar tool was already in use but of Swedish origin, and that at some point the use of an English variant of the same was widespread, which later became commonly known as a key. “English”, in fact, just to underline the difference from the original Swedish on which it was based; even in this case, however, we enter unstable terrain made up mostly of “legends”.

In truth it is not possible to ascertain with certainty the precise moment and why this tool, in Italy, was defined as such, the only certain thing is that custom has transformed what originally wanted to be a simple attribute, into a true definition. and proper.

How to use a wrench

Where to buy a wrench

The purchase of a wrench, as well as that of any other hand tool intended for DIY or professional use, should normally be done in person. The most important thing in this case, in fact, is the possibility of being able to closely examine the tool and “touch it with your hand” to test the characteristics and quality of the materials with which it is manufactured.

Like most tools and hand tools, wrenches can also be easily found in hardware stores or in large chains specializing in the sale of DIY items.

The Web option

In any case, it is also possible to buy online, of course, both from the sites of authorized resellers and on e-commerce platforms, such as Amazon for example; in this case, however, since you do not have the opportunity to personally verify the quality of the product, it is advisable to pay due attention to product reviews and avoid, as far as possible, buying those with too low cost.

On the other hand, the possibility of choice is far greater than buying in the store, and therefore it becomes easier to find models that are usually scarce, such as the flat head wrench.

Remove the rust

If you have a wrench (but actually any other tool) that has been attacked by rust, there is a natural method to eliminate it in a simple way, which is by creating a sort of paste with salt and lemon. As? Just put some fine salt and lemon juice in a bowl (with the ratio of three to one) and then spread this mixture on the rusty surface of the instrument. Wait about half an hour and then remove the paste with a damp sponge. The rust will also come off with it.
