Widely used in DIY, in the assembly of your furniture but also in the field of cycling, the hex key is one of the most famous DIY tools. The hex key or the Allen wrench is in most cases presented in an L-shape with the same gauge on both sides, so it can be used on either side. The purpose of the L-shape is to make it easy to use with its arm as a lever but also to make it possible to use it in tight places. Here is a very nice kit from the German brand Ronix Tools that offers a set of 9 short-arm hex keys, all stored in a beautiful storage box for quick access to all the wrenches. Ronix RH-2033 includes the following Allen key sizes: 1.5, 2, 2.5, 3, 4, 5, 6, 8, and 10 mm.
