Metric DIN 975 Class 4.6 All Thread Rods with Clear Cr3 Zinc Plating

Metric DIN 975 Class 4.6 All Thread Rods – Clear Cr3 Zinc Plated

Light-Duty Threaded Rods with Enhanced Corrosion Protection

Metric DIN 975 Class 4.6 all thread rods with Clear Cr3 zinc plating provide a reliable and economical solution for light-duty fastening and bracing applications, especially where moderate corrosion resistance is required. These rods are ideal for indoor, dry environments, or covered outdoor applications in construction, HVAC, and general-purpose fabrication.

What Is DIN 975 Class 4.6?

DIN 975 specifies the dimensions and threading for fully threaded metric rods, commonly used in assembly and anchoring systems. Class 4.6 designates a low-carbon steel construction with moderate tensile strength, suitable for non-critical load-bearing applications.

These rods are fully threaded, offering versatile installation options and compatibility with standard DIN 934 metric hex nuts and DIN 125 flat washers.

Benefits of Clear Cr3 Zinc Plating

The Clear Cr3 (trivalent chromium) zinc plating provides a thin, bright silver finish that resists oxidation and adds a clean, professional appearance. Key advantages include:

• ✅ Corrosion resistance in mildly humid or dry conditions

• ✅ RoHS-compliant trivalent coating (eco-friendly alternative to hexavalent chrome)

• ✅ Smooth, uniform surface ideal for visible installations

• ✅ Excellent for indoor mechanical, architectural, or utility projects

Common Sizes and Uses

DIN 975 Class 4.6 rods are available in sizes from M6 to M30, in 1-meter and 2-meter standard lengths. Typical applications include:

• Electrical conduit and cable tray supports

• Equipment mounting and framing

• HVAC duct suspension and light fixtures

Reliable, Cost-Effective Fastening with a Clean Finish

For dependable, corrosion-protected fastening, Metric DIN 975 Class 4.6 all thread rods with Clear Cr3 zinc plating are the ideal choice for general-purpose metric applications.
