In today's market, fasteners are available in a very wide range. If we talk about
bolts, they accept bending loads, tensile loads, and shear loads. Therefore, with a high level of efficiency, they are used to connect the elements of various structures, ranging from flanges and ending to the frames of future sports facilities. Bolts with strength class 8.8 and above are considered high-strength. Alloy steels or carbon steels with carbon content not exceeding 0.5% are used for their production. The main advantage of these products is the use of high-strength bolts with a smaller diameter and weight
