In most cases, a bolt with a hexagonal head and full thread DIN 933, due to the presence of a thread along the entire length of the rod, is used for fastening thin-sheet elements in fairly light structures, when the acting load is mainly directed along the rod itself. If this feature of fastening is not taken into account and such a metal product is used in a heavy structure to connect individual nodes, then the static load of the structure itself can simply flatten the thread, and the dynamic load will reduce its strength.

The main field of application of such products is construction and mechanical engineering, although they are widely used in other production areas.

The presence of a thread along the entire length allows you to use bolts of this configuration with almost any size of the elements to be fastened, you can be limited only by the length of the bolt itself. To strengthen the fastening, manufacturers recommend using DIN 934 nuts and DIN 125 washers. Moreover, the majority of such bolted connections are in metal structures and only a few – in wooden or plastic ones. And the installation itself takes a very short period of time, because it can be done with the simplest hand tools – a wrench or an electric tool with a socket head.
