GOST 15163-78 Conical bolts of increased accuracyBolts GOST 15163-78 are conical bolts of increased accuracy with a thread diameter from 4 to 16 mm. 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.
Description of the product design and its features
threaded rod. Products must be manufactured with accuracy class A and B.
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 electroplating workshop. A multilayer coating is also available, such as copper-nickel (M.N.) or copper-nickel-chromium (M.N.X.6).
