DIN 6927 Hexagon Flange Nut, Self-Locking
FLOK supplies self-locking DIN 6927 flange nuts, property class 8, 10, 12 steel, thread diameter M6–M20, zinc, nickel, chrome coatings.
DIN 6927 is a manufacturing standard for self-locking hexagon nuts with an additional flange. These products prevent the threaded connection from spontaneously unwinding, and the flange eliminates the need for additional washers and lock washers.
The underside of the flange can be serrated — in this case it provides an additional secure bond with the material and prevents the connection from loosening. The nut is all-metal, so it can be used in any conditions.
Nut materials
The base material is St carbon steel, property class 8, 10 or 12. High-strength nuts are designed for significant mechanical loads and are used together with bolts, screws and studs of similar strength. To increase corrosion resistance, the metal is given a protective coating of zinc, nickel or chrome, applied by the electroplating method.
Zinc-plated or nickel-plated nuts are resistant to moisture and chemically aggressive environments, so they can be used in any conditions. All-metal fasteners are designed for long-term operation even under heavy constant loads.
Characteristics and features
Dimensional parameters of the nuts:
- Thread hole diameter — from M6 to M20.
- Overall product height — from 7.3 to 22.4 mm.
- Width across flats of the product — from 10 to 30 mm.
- Maximum flange diameter of the nut — from 14.2 to 42.8 mm.
Similar fastener products are manufactured to the international standards EN 1664, ISO 7044, as well as to the Russian GOST R ISO 7044-2009. Analogues may have minor dimensional deviations, so it is necessary to consult with specialists when selecting fasteners.
Application possibilities and supply conditions
Self-locking all-metal nuts are used in various branches of industrial production: in the manufacture of automobiles, machine tools, special equipment, in mechanical engineering, shipbuilding, instrument making and other fields. This type of fastener improves the reliability of fixing parts of assemblies and units.
FLOK supplies fasteners of this type. Consult with specialists to select the right fasteners.
