DIN975 Threaded Rod Black Oxide

The DIN975 threaded rod black oxide is made of high - quality carbon steel or alloy steel. These materials offer good mechanical properties, such as high strength, toughness, and wear resistance, enabling the threaded rod to withstand heavy loads and harsh working conditions.

The black oxide coating is applied to the surface of the threaded rod. This coating not only provides a certain degree of corrosion resistance, protecting the rod from rust and oxidation in harsh environments, but also gives the rod a black - colored appearance, which is aesthetically pleasing and can be used in some applications where appearance is important.

The DIN 975 threaded rod with a black oxide finish is a metric fully threaded rod (also called a stud or screw rod) that meets the German Institute for Standardization (DIN) specifications. Here’s what you need to know:

Key Features:

Material: Typically made from carbon steel (e.g., Grade 4.8, 8.8, or higher).

Finish: Black oxide coating for corrosion resistance and a dark, matte appearance.

Thread Type: Metric coarse or fine threads (most commonly M6, M8, M10, M12, etc.).

Length: DIN 975 specifies 1-meter standard lengths, but other lengths (e.g., 2m, 3m) may be available.

Standards: Complies with DIN 975 (metric threaded rods) and sometimes ISO 898-1 for mechanical properties.

Common Applications:

General construction & machinery

Automotive & industrial assembly

Fastening in corrosive environments (black oxide provides mild protection)

Furniture, scaffolding, and structural supports

Advantages of Black Oxide Finish:

Improves corrosion resistance vs. plain steel

Reduces light reflection (non-glare surface)

Enhances aesthetics while maintaining thread tolerances

Alternative Finishes:

Zinc-plated (better corrosion resistance)

Stainless steel (A2/A4 for high corrosion resistance)

Hot-dip galvanized (heavy-duty protection)
