Hexagon nut

The hexagon nut is manufactured to the German standard DIN 555. It is equivalent to fasteners produced under the Russian standards GOST 5927-20, GOST 5915-70 and the international standard ISO 4034. It is the most universal fastener, widely used across various fields of manufacturing and industry. It is tightened with an adjustable wrench.

Hexagon nuts are manufactured from various materials: steel of property class 6-12, coated steel (yellow chromate plating, hot-dip and electrolytic galvanizing), stainless steel of class A2, austenitic corrosion-resistant stainless steel of class A4, non-ferrous metals (brass, aluminium) and their alloys, plastic (high-strength polyamide).

Nuts of this type are produced in a wide range of sizes. The thread diameter ranges from M5 to M60, the outer diameter is 8.63–104.86 mm, and the height is from 4 to 51 mm.

The application of the fastener depends on the material it is made of. The highest requirements apply to hexagon nuts made of non-magnetic, corrosion-resistant steel — they can be used even in aggressive environments.

FLOK supplies the hexagon nut DIN 555 from stock and made to order.
