Stainless Steel Nyloc Nuts DIN 982 ISO 7040 Lock Nut A2-70 Prevailing Torque Type Hexagon Nuts with Nonmetallic Insert 304

Description

Stainless steel nyloc nuts also known as prevailing torque lock nuts, are hexagon nuts with a nonmetallic nylon insert that provides enhanced locking capabilities. Conforming to DIN 982 and ISO 7040 standards, these A2-70 stainless steel lock nuts offer excellent resistance to vibration, loosening, and corrosion. Ever Hardware provides custom made fasteners and customizable packaging.

1. Excellent Locking Mechanism

The nylon insert in the Nyloc nut creates friction against the bolt threads, increasing resistance to loosening. This prevailing torque feature ensures that the nut stays securely in place, even in high-vibration environments, such as automotive, aerospace, and industrial machinery.

2. Superior Corrosion Resistance

Made from A2-70 stainless steel (304 grade), these lock nuts provide excellent resistance to rust and oxidation. They are ideal for marine, outdoor, and chemical exposure applications, where standard steel nuts would quickly corrode.

3. Resistance to Shock and Vibration

Unlike standard hex nuts, which may loosen over time due to vibration, Nyloc nuts absorb shocks and dynamic forces, making them perfect for high-speed machinery, railways, and structural assemblies that experience constant movement.

4. No Need for Additional Locking Mechanisms

These nuts eliminate the need for lock washers, thread-locking adhesives, or double-nut configurations, simplifying assembly while reducing costs and installation time.

5. High Strength and Load Capacity

With an A2-70 tensile strength rating, these nuts can withstand moderate to heavy loads, making them suitable for engineering, construction, and mechanical applications requiring secure fastening.

6. Reusable with Proper Handling

While the nylon insert will eventually wear out after multiple uses, Nyloc nuts can be reused several times before replacement is needed, unlike one-time-use thread-locking adhesives.

7. Easy Installation and Compatibility

Manufactured to DIN 982 and ISO 7040 standards, these nuts offer precise dimensions and are fully compatible with standard metric bolts and screws, ensuring easy integration into existing fastening systems.

8. Temperature and Chemical Resistance

The nylon insert remains effective in moderate temperatures, and stainless steel provides good resistance to chemicals, making these nuts reliable in varied industrial environments.

9. Cost-Effective and Maintenance-Free

By preventing self-loosening, these nuts reduce maintenance requirements and increase safety, leading to long-term cost savings.

Conclusion

Stainless steel Nyloc nuts (DIN 982, ISO 7040, A2-70) provide a secure, corrosion-resistant, and vibration-resistant fastening solution. Their nylon insert locking mechanism, high strength, and ease of use make them essential for automotive, construction, aerospace, and industrial applications where reliability is critical.
