After buying the folding hex key set, one has to begin using it. But before using the tool, it is necessary to know the capacity and precautions.

For this, it is better to read the instructions manual and understand the working and safety norms associated with it. This step is essential because some folding hex key sets are difficult to use and involve a complex procedure. Hence, it is advisable to read the guide for easy and quick usage.

Step 3: Check the size of the screw/bolt

It is an important step of the entire process. One has to measure the dimensions of the screw/ bolt that has to be tightened using the hex key set. This is because screws and bolts are of varied sizes, and therefore, the size of the hex key also differs.

It is, however, possible to know the screw’s size only by looking at it, but one can also assess it by positioning each hex key into the screw. This step further helps to know whether a specific hex key set is appropriate or not. A proper set includes hex keys of every size, ranging from 1mm to 10mm.

Step 4: Folding a specific hex key

After knowing the size of the screw and finding the suitable hex key. The next step is to fold it from the set. A folding hex key is normally folded out at different angles, such as 90-degrees, 135-degrees, and 180-degrees from the pack to provide maximum torque.

A particular amount of torque is necessary for obtaining the desired results. Further, one can easily manage all the keys at a single time and eliminates the risk of losing any of them.

So, one has to hold a hex key, push it upward, and adjust it at a specific angle to get the best outcomes without any problem.

Step 5: Place the key’s tip into the bolt/screw

The last step in this procedure is to place the selected and appropriate hex key into the screw. An individual has to place the key’s head or tip into the hexagonal cross-section of the screw and apply the proper amount of pressure into it.

Then, it has to be turned in a clockwise direction until the bolt is adequately tightened. However, it is important to note that the wrong position or inappropriate pressure can damage the hex key and can affect its quality. It can also deteriorate the original shape of the key that can make the screw tightening task more difficult and complex.

Thus, it is better to understand every aspect of a floating hex key set before using it. Hence, an individual has to follow all these steps to use this hand tool correctly and achieving professional results with every DIY project. Lastly, it is essential to store them properly so that it can be used in the future without any damage to the key’s quality and performance.
