Stainless Steel Hex Thin Nuts DIN 439 Metric 304 A2 Hexagon Jam Nut ISO 4035 Coarse Thread

Description

Stainless steel hex thin nuts DIN 439, also known as jam nuts, are designed to provide a secure and space-saving fastening solution. Conforming to DIN 439 and ISO 4035 standards, these A2-304 stainless steel nuts offer excellent corrosion resistance, durability, and versatility. Ever Hardware provides custom made fasteners and customizable packaging.

1. Superior Corrosion Resistance

Made from A2-304 stainless steel, these nuts offer excellent resistance to rust and corrosion, making them ideal for marine, outdoor, and humid environments. Unlike standard carbon steel nuts, they do not require additional coatings and maintain their integrity over time, even in exposure to water or chemicals.

2. Space-Saving and Lightweight Design

As thin-profile nuts, they take up less space than standard hex nuts, making them ideal for applications where clearance is limited. They are commonly used in electronics, automotive, and machinery, where minimizing size and weight is crucial.

3. Reliable Locking Function

Hex thin nuts are frequently used as locking nuts when paired with a standard hex nut. This technique, known as double nut locking, helps prevent loosening due to vibration, making them suitable for high-movement or dynamic applications, such as industrial machinery, engines, and mechanical systems.

4. High Strength and Durability

Stainless steel 304 provides good tensile strength and wear resistance, ensuring that the nuts can withstand moderate to heavy loads while maintaining long-term durability. This makes them suitable for structural, mechanical, and high-stress environments.

5. Coarse Thread for Easy Installation

The coarse thread (ISO 4035) design offers better resistance to stripping and cross-threading, making installation and removal faster and more user-friendly compared to fine-threaded alternatives. Coarse threads also perform better in harsh conditions, such as dirty or high-vibration environments.

6. Standardized for Easy Replacement

These nuts are manufactured to DIN 439 and ISO 4035 standards, ensuring dimensional accuracy and compatibility with other metric fasteners. This allows for easy replacement, interchangeability, and integration into existing systems.

7. Aesthetic and Hygienic Properties

The smooth and polished surface of stainless steel 304 is not only visually appealing but also resistant to dirt accumulation, making it an excellent choice for food processing, medical, and pharmaceutical applications where cleanliness is essential.

8. Temperature and Chemical Resistance

These nuts can withstand high and low temperatures, ensuring reliable performance in extreme environments such as automotive engines, chemical processing, and outdoor installations.

9. Reusability and Low Maintenance

Unlike coated or treated steel nuts, stainless steel A2-304 does not degrade easily. This makes them a cost-effective and reusable option, reducing the need for frequent replacements and maintenance.

10. Environmentally Friendly Choice

Stainless steel is 100% recyclable, making these nuts a more sustainable and eco-friendly fastening solution compared to plated or treated carbon steel alternatives.

Conclusion

Stainless steel hex thin nuts (A2-304, coarse thread) DIN 439 / ISO 4035 offer a corrosion-resistant, strong, and space-saving fastening solution for a wide range of applications. Their locking capability, durability, and ease of use make them ideal for industrial, mechanical, automotive, and structural uses, ensuring reliable performance in demanding environments.
