GOST 15524-70 Hexagon nuts high accuracy class ANuts GOST 15524-70 – this product is a hexagonal rod with an internal hole and an internal thread, suitable for fastening metal structures. 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
Material of manufacture: from steel grades 40X, A12.
Coating of nuts with zinc, chromium, nickel, cadmium, etc. is carried out in our own galvanic workshop. A multilayer coating is also available, such as copper-nickel (M.N.) or copper-nickel-chromium (M.N.X.6).
