Stainless Steel 316 Hex Thin Nuts DIN 439 A4 Hexagon Jam Nut ISO 4035 Coarse Thread

Description

Stainless steel 316 hex thin nuts DIN 439 also known as jam nuts, are designed for secure fastening in limited-space applications while providing excellent corrosion resistance. The DIN 439 / ISO 4035 standard ensures precise dimensions and compatibility with metric fasteners. Using A4-316 stainless steel, these nuts offer enhanced durability, making them ideal for marine, chemical, and industrial applications. Ever Hardware provides custom made fasteners and customizable packaging.

1. Exceptional Corrosion Resistance

Made from A4-316 stainless steel, these nuts offer superior resistance to rust, oxidation, and chemical exposure compared to A2-304 stainless steel. This makes them ideal for marine, coastal, chemical processing, and outdoor applications where exposure to moisture, salt, and harsh chemicals is common.

2. High Strength and Durability

A4-316 stainless steel provides higher tensile strength and better mechanical properties than standard A2-304 stainless steel. This allows these jam nuts to perform reliably under high-stress conditions, making them suitable for industrial, mechanical, and structural applications.

3. Coarse Thread for Quick Installation

Coarse threads offer several benefits:
• Faster assembly and disassembly, reducing installation time.
• Better resistance to stripping and cross-threading, making them easier to work with in harsh environments.
• Superior performance in dirtier conditions, such as construction and heavy machinery applications.

4. Locking Function for Secure Fastening

These thin-profile jam nuts are commonly used as locking nuts in combination with a standard hex nut. The double-nut locking mechanism helps prevent loosening due to vibrations and dynamic loads, making them suitable for automotive, aerospace, and heavy-duty machinery.

5. Space-Saving and Lightweight

The thin design makes them ideal for applications where clearance is limited and a standard hex nut would be too bulky. They are widely used in precision instruments, electronics, and compact mechanical assemblies.

6. Excellent Resistance to Extreme Temperatures

A4-316 stainless steel performs well in high and low temperatures, making these nuts suitable for:
• Cryogenic applications
• High-temperature environments like exhaust systems and industrial furnaces

7. Hygienic and Easy to Clean

The smooth, non-porous surface of stainless steel 316 prevents dirt accumulation, making it ideal for food processing, medical equipment, and pharmaceutical applications where hygiene is essential.

8. Standardized for Easy Replacement

Manufactured according to DIN 439 and ISO 4035 standards, these nuts are dimensionally accurate and interchangeable with other metric fasteners, allowing for easy integration and replacement.

9. Reusability and Low Maintenance

Unlike coated steel nuts that require frequent replacements due to rust, A4-316 stainless steel is highly durable, reducing maintenance costs and increasing longevity. This makes them a cost-effective solution over time.

10. Environmentally Friendly Choice

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

Conclusion

Stainless steel 316 hex thin nuts (A4-316, coarse thread) DIN 439 / ISO 4035offer a high-strength, corrosion-resistant, and space-saving fastening solution. Their marine-grade durability, vibration resistance, and extreme temperature tolerance make them ideal for offshore, industrial, automotive, medical, and structural applications where reliability is crucial.
