Bolts in accordance with GOST 8711-70 are almost universal fasteners, since the thread goes along a whole rod, they can connect several parts at once, securing them with nuts. Used together with nuts (hex, square, welded). For a more durable connection, washers (grovers) can be used.Bolts GOST 8711-70 – threaded fasteners along the whole rod. 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.
The bolt design consists of a hex head and a cylindrical rod with full threads. The requirements for the accuracy class are imposed on the products, the standard provides for the accuracy class A.
Made of steel (normal or stainless), aluminum, PA 6.6 polyamide, brass, non-ferrous metal alloys with strength class 5.6; 5.8; 8.8; 10.9; 12.9. Or others as agreed with the customer.
Bolts are coated with zinc, chromium, nickel, cadmium, etc. in our own galvanic workshop. Multilayer coatings are also available, such as copper-nickel (MN) or copper-nickel-chromium (MNX.6).
