DIN 6915 Hexagon High-Strength Nut, Zinc-Plated Steel

The DIN 6915 standard applies to the manufacture of high-strength hexagon nuts. They are used to create threaded connections designed for continuous high mechanical loads. These nuts are intended for use together with EN 14399 high-strength bolts, forming strong connections for parts, assemblies and structures. Thanks to the hexagon shape, the nut is tightened with a wrench or installed with a nut runner.

Manufacturing features

Material — carbon steel of property class 10, designed for intensive mechanical stress. The products comply with product grade B. To extend service life, the steel is coated with a thin layer of zinc — galvanizing is performed by the electroplating method. The anti-corrosion coating allows the fasteners to withstand high operating loads and prolonged contact with moisture and aggressive environments.

Technical characteristics:

• Hole thread diameter — from M12 to M36.
• Maximum product height — from 10 to 29 mm.
• Width across flats — from 22 to 60 mm.
• Hole thread pitch — from 1.75 to 4 mm.

The closest equivalent is manufactured to the international standard EN 14399-4, with virtually no differences between them. When choosing an equivalent, it is necessary to verify the dimensions.

Conditions of use

High-strength nuts with zinc coating are used in industry, construction and other fields. They are used for assembling loaded units and assemblies in the manufacture of vehicles, machine tools, instruments, as well as for assembling high-strength metal frames and other structures. They can be used together with washers of various types made of similar material.
