M6-M30 DIN6334 Hex Long Nuts

M6-M30 DIN6334 Hex Long Nuts main parameters

Standards:
DIN 6334: This is a standard developed by the German Industrial Standards Committee (Deutsches Institut für Normung, DIN) that specifies the dimensions, tolerances and performance requirements for hexagonal long nuts.

Size:
M6-M30: This means that the thread diameter of the nut varies from M6 (i.e. 6 mm) to M30 (i.e. 30 mm). Nuts of different sizes are often used to match bolts or threaded rods of different diameters.

Surface treatment:
Original color: The original metal color of the nut without any additional coating.
Zinc plated: Coating a nut with a layer of zinc to increase its corrosion resistance and durability.
Black: Nuts may be oxidized or otherwise treated to obtain a black appearance.
Dacromet: This is a metal surface treatment process that provides excellent corrosion resistance by applying a zinc-aluminum alloy coating to the metal surface.

Material:
Carbon steel: A common metal material widely used because of its high strength and relatively low cost.
Stainless steel: An alloy steel with excellent corrosion resistance, often used in applications requiring high corrosion resistance.

Features
Hexagonal shape: The hexagonal shape of the nut allows it to be easily tightened or loosened using tools such as a wrench or screwdriver.
Long design: Compared with standard nuts, the long design can provide greater tightening torque and stronger connection force.
Various surface treatments: Different surface treatments can meet different application requirements, such as corrosion resistance, aesthetics, etc.
Multiple material options: Depending on the application needs, carbon steel or stainless steel can be selected as the material to meet different strength and corrosion resistance requirements.

Application areas
M6-M30 DIN6334 Hex Long Nuts can be widely used in various machinery, equipment and structures for connecting and fixing bolts or screws. Its long design and excellent performance make it particularly popular in applications requiring high joint strength and corrosion resistance.
