GOST 15591-70 Bolts with hexagon reduced head of accuracy class C

Bolts in accordance with GOST 15591-70 – These bolts are used in many industries. Increased demand for products, in particular, is observed in the aircraft and machine-building industries, as well as in construction, energy and metalworking, where they are used for reliable fastening of parts and metal structures. Use will also require nuts (hex, square, or weld). The use of washers of various configurations (grovers, flat, etc.) will help to make the connection more reliable.
