DIN 2510 Hexagon Nut Stainless for Studs with Reduced Shank

Special nuts designed for studs with a reduced shank are manufactured to DIN 2510. They have a hexagonal shape complemented by a conical end. This allows the nut to fasten securely onto a stud with a decreasing diameter.

This type of fastener is used to create strong flange joints and is in demand across various branches of mechanical engineering, as well as in the assembly of steel structures. A distinctive feature of the fastener is its ability to withstand high temperatures due to the heat resistance of the metal.

Materials

Special nuts for studs are made from stainless steel of composition 21CrMoV57. This alloy can withstand exposure to high temperatures for a long time. The metal does not lose its original strength when heated to 525 degrees Celsius, which allows nuts made from it to be used in industrial workshop conditions and various types of equipment. Hexagon nuts of this type are resistant to relaxation stress.

Stainless steel is not subject to corrosion: it is not affected by prolonged contact with moisture and is resistant to chemically aggressive environments. Fasteners made from alloys with a high content of molybdenum, tungsten and chromium are distinguished by high strength and a long service life.

Technical specifications

This type of fastener is produced in the following range of main sizes:

• Thread diameter — from M12 to M56.
• Overall height of the product — from 12 to 56 mm.
• Width across flats of the nut — from 22 to 85 mm.
• Diameter of the upper part of the nut — from 21 to 83 mm.

Nuts of this type have no common equivalents in other standardization systems.

Applications

Heat-resistant nuts, designed for joint use with studs with a reduced shank, are widely used in industry. Fasteners of this type are used in automotive manufacturing, in the production of machine tools and other types of industrial equipment. The fastener is designed for long-term operation under demanding conditions. It is also used in the installation of industrial utility lines and the assembly of steel structures.
