In what situations will an Allen key be useful?
The Allen key, also known as a hexagonal or ampule key, is a small and inconspicuous tool with great possibilities, so it is useful in many different areas of life. It is characterized by a simple construction and versatility, which is why it is used by many specialists - mechanics and electricians. It is of course an irreplaceable piece of equipment for every DIY enthusiast. Often found in sets for assembling furniture or bicycles. The main task of the Allen key is to unscrew and tighten hexagonal screws. So you can say that without this key you can't do anything.
Every cyclist will admit that they should always have this inconspicuous wrench with them - not only in the workshop, but also when travelling. Thanks to it, we can adjust the springs in the brakes, tighten the handlebars, saddle, or adjust the derailleurs. This is a double-sided tool, and the choice of the tip depends on the task we need it for. As a rule, the tip of the shorter arm allows for achieving greater torque, while the tip of the long arm is ideal if we want to reach hard-to-reach places.
It is also commonly used in more specialist areas, such as electronics. It is invaluable when repairing or assembling electronic devices, especially those requiring precise tightening of small screws. The Allen key does this job precisely, and because it always achieves the right torque, there is no risk of damaging delicate components.
What types of Allen keys are there?
Although the Allen key may seem like a simple tool, it is worth knowing that it comes in many forms. There are several types of such keys, which we will discuss now.
The main division concerns L-type and T-type Allen keys. The first one is the most common, universal, double-sided. As its name suggests, it resembles the letter L. It usually has no handle, so it is suitable for light work that does not require force.
The T-type Allen key has two arms that form the shape of this letter, hence its name. It is a great solution if we are dealing with more complicated and specialized tasks. Equipped with a handle, it is able to unscrew hard-set, seized screws. The Allen key with a handle has a similar character, used to unscrew rusty and otherwise blocked screws.
A multi-function Allen key, which looks like a penknife, is also a popular choice. An interesting solution is an insulated Allen key, chosen especially by electricians, because it can be used in places under voltage. Another type is a ball Allen key, which has a ball on one of the arms, which allows work at an angle. The inclination can be up to 30 degrees, especially in places where it is difficult to reach with other tools.
