Stainless Steel 316 Nyloc Nut DIN 985 ISO 10511 Nylon Lock A4-70 Prevailing Torque Type Hexagon Thin Nuts with Nonmetallic Insert

Description

The stainless steel 316 nyloc nut (DIN 985, ISO 10511, A4-70) are prevailing torque hexagon thin nuts equipped with a nonmetallic nylon insert that provides excellent resistance against loosening due to vibration. Made from marine-grade 316 stainless steel (A4-70), these nuts offer exceptional corrosion resistance, high strength, and durability, making them ideal for harsh environments such as marine, chemical, and industrial applications. Ever Hardware provides custom made fasteners and customizable packaging.

1. Superior Corrosion Resistance

Manufactured from A4-70 stainless steel (316), these nuts provide exceptional resistance to rust, oxidation, and chemical exposure, making them perfect for marine, offshore, and industrial environments. They perform well in high-moisture, saltwater, and acidic conditions, where standard A2-70 (304) nuts may corrode over time.

2. Secure Locking Mechanism

The nylon insert inside the nut creates friction against the bolt threads, preventing self-loosening due to vibration, impact, or dynamic loads. This makes them ideal for high-speed machinery, automotive, aerospace, and heavy-duty applications where reliable fastening is essential.

3. Thin and Space-Saving Design

Being a thin hex nut, it is more compact than standard Nyloc nuts, making it ideal for applications with limited space such as electrical enclosures, precision instruments, and lightweight mechanical assemblies.

4. High Strength and Load Capacity

With an A4-70 tensile strength rating, these nuts offer strong mechanical performance, making them suitable for medium to heavy-load applications in structural, construction, and marine engineering.

5. Eliminates the Need for Additional Locking Devices

The built-in nylon insert removes the need for lock washers, thread-locking adhesives, or double-nut configurations, reducing assembly time and costs while ensuring a reliable fastening system.

6. Resistance to Vibration and Shock

The nylon insert absorbs shocks and vibrations, keeping the nut securely in place even in high-impact, high-speed, or rotating applications, such as engines, turbines, pumps, and railways.

7. Excellent Chemical and Temperature Resistance

A4-70 stainless steel offers superior resistance to harsh chemicals, acids, and chlorides, making these nuts ideal for food processing, chemical plants, and offshore platforms. While the nylon insert has temperature limitations, the nut itself can withstand high and low-temperature environments better than A2-70 stainless steel.

8. Reusability and Cost Efficiency

While nylon inserts wear out after multiple uses, these nuts can still be reused a few times, offering a cost-effective alternative to single-use thread-locking adhesives. Their durability reduces maintenance and replacement costs over time.

9. Compliance with International Standards

Manufactured according to DIN 985 and ISO 10511, these nuts ensure dimensional accuracy and compatibility with standard metric bolts, making them easy to integrate into existing fastening systems.

Conclusion

Stainless steel 316 Nyloc nut (DIN 985, ISO 10511, A4-70) provides a secure, corrosion-resistant, and vibration-proof fastening solution. Their marine-grade stainless steel construction, thin profile, and durable nylon locking mechanism make them ideal for marine, chemical, automotive, aerospace, and heavy-duty industrial applications where strength, reliability, and long-term performance are critical.
