High Hexagon Nut

Hexagon nuts manufactured to the German standard DIN 6330 are similar in shape and size to domestically produced fasteners under GOST 15523-70. Main fields of application: machine building, hydroelectric power plant construction, construction, including high-rise buildings, instrument engineering, and other industries.

The nuts have metric thread. Diameter: M8–M42. Fastener height: 9–72 mm. Property class: 8 and 10. The spherical end face of the part simplifies unscrewing and tightening and increases the strength of the joint. The nut is screwed onto a stud, screw or bolt with a matching thread.

High hexagon nuts are made of various materials: food-grade stainless steel grade A2, carbon steel, corrosion-resistant non-magnetic austenitic stainless steel grade A4, coated steel (electrogalvanized), non-ferrous metals (brass and aluminium) and their alloys.

Nuts made of corrosion-resistant steel are the most common. Their strength is designed for increased loads, so they are used where there is increased tension, temperature fluctuations, or exposure to aggressive environments.
