Hex head bolts with countersunk flange are used in the automotive and automotive industries for suspension systems, braking systems and control systems. They are also used in the connections of elements that require a large bearing surface - incl. in photovoltaic installations.
Our offer includes DIN 6921 screws in sizes from M4 to M20. They usually come in two strength classes: 8.8 and 10.9, and also, on special request, in class 12.9. They come from the most renowned manufacturers, which ensures their durability and safety of use.
In standard terms, they are made of carbon steel without a protective coating, but they can also be electro-galvanized or zinc flake-coated. In the production of A2 stainless steel, ISO 4162 bolts can be used in wet rooms and in the external space, and thanks to their structure of A4 acid-resistant steel, they can be used in an industrial atmosphere and near water reservoirs.
