Product Details
Our DIN 577 Yellow Zinc Plated Square Nuts are manufactured to deliver reliable performance and extended service life in moderate to harsh environments.
- Enhanced Corrosion Resistance (Yellow Zinc Plating): This finish, also known as color or yellow galvanized, involves electro-galvanizing the carbon steel nut and then applying a yellow chromate conversion coating. This process provides significantly better corrosion resistance than standard clear (white-blue) zinc plating, making it an excellent and cost-effective choice for applications with exposure to moisture, rain, and fluctuating temperatures. The distinctive gold/yellow iridescent finish is a hallmark of this protective coating.
- High-Strength Carbon Steel Core: The nut is manufactured from high-quality carbon steel and is available in a range of property classes, including Class 4.8 for general use and high-strength classes like 8.8, 10.9, and 12.9 for demanding, load-bearing connections. This ensures you can select the appropriate strength for your specific structural or machinery requirements.
- The DIN 577 Square Advantage: The primary feature of these nuts is their four-sided shape. This geometry provides a much larger gripping surface for a wrench, allowing for high-torque tightening. More importantly, it is ideal for being captured in a square channel or held against a flat surface, which prevents the nut from turning while a bolt is tightened. This makes assembly easier, especially in blind spots, and provides excellent resistance to loosening from vibration.
- Standardized for Reliability: Manufactured in strict accordance with the DIN 577 standard, our square nuts guarantee uniform dimensions, thread profiles, and quality. This ensures a consistent, secure, and professional fit for every application, from mass production to one-off projects.

Product Features
Our DIN 577 Yellow Zinc Plated Square Nuts are a top choice for their functional design and robust finish.
- Enhanced Corrosion Protection: The yellow zinc chromate coating offers superior resistance to rust and corrosion compared to clear zinc, ideal for outdoor and industrial use.
- Excellent Anti-Loosening Performance: The square shape locks against flat surfaces and in channels, effectively resisting rotation and loosening caused by vibration.
- Large Wrenching Surface: The four flat sides provide a secure grip for wrenches, enabling easy and high-torque tightening.
- Cost-Effective Durability: Offers a great balance of enhanced corrosion resistance and strength at a more economical price point than stainless steel.
- Multiple Strength Options: Available in various steel property classes to match the load requirements of your specific assembly.
- DIN 577 Compliance: Guarantees dimensional accuracy, quality, and interchangeability for all your fastening needs.
Product Applications
The combination of a robust shape and a protective finish makes these nuts highly versatile.
- Automotive Industry: Widely used for chassis fastening and under-body components where resistance to road spray and environmental elements is required.
- Construction and Structural Connections: Ideal for outdoor structures, framing, and other connections where enhanced weather resistance is necessary.
- Heavy Industry and Machinery: Perfect for assembling heavy equipment and machinery that operates in demanding industrial environments.
- Agricultural Equipment: Provides durable, weather-resistant fastening for tractors, harvesters, and other farm implements exposed to the outdoors.
- General Industrial Use: A reliable choice for any application requiring a strong, corrosion-resistant fastener with excellent anti-rotation properties.
