Nyloc Nut DIN 982 ISO 7040 Lock Nut Stainless Steel A4-80 Prevailing Torque Type Hexagon Nuts with Nonmetallic Insert 316

Description

Nyloc nut DIN 982 designed according to DIN 982 and ISO 7040, are prevailing torque lock nuts with a nonmetallic nylon insert that provides superior resistance to vibration and loosening. Made from A4-80 stainless steel (316 grade), these nuts offer enhanced strength and corrosion resistance, making them ideal for marine, chemical, and high-performance applications. Ever Hardware provides custom made fasteners and customizable packaging.

1. Superior Corrosion Resistance

A4-80 stainless steel is marine-grade 316 stainless steel, which offers exceptional resistance to rust, oxidation, and chemical exposure. This makes these Nyloc nuts perfect for offshore structures, marine engineering, wastewater treatment plants, and chemical processing industries.

2. High Strength and Load-Bearing Capacity

With an 80 tensile strength rating, A4-80 Nyloc nuts are significantly stronger than standard A2-70 nuts. They can withstand higher loads, heavy-duty applications, and extreme environmental conditions, making them ideal for construction, industrial machinery, and structural fastening.

3. Reliable Locking Mechanism

The nylon insert inside the nut creates friction with the bolt threads, preventing self-loosening due to vibration or dynamic forces. This ensures a secure and long-lasting connection, even in high-impact and high-speed applications, such as railways, automotive, and aerospace.

4. Eliminates the Need for Additional Locking Devices

Nyloc nuts replace the need for lock washers, thread-locking compounds, or double-nut systems, simplifying installation and reducing maintenance time and costs.

5. Vibration and Shock Resistance

The nylon insert absorbs shocks and impacts, reducing the risk of loosening over time. This makes A4-80 Nyloc nuts suitable for heavy machinery, turbines, pumps, and industrial motors that experience constant movement.

6. Temperature and Chemical Resistance

316 stainless steel provides superior resistance to extreme temperatures, while the nylon insert remains effective in moderate heat conditions. This makes these nuts ideal for harsh industrial environments, marine applications, and food processing industries.

7. Reusability with Proper Handling

While the nylon insert wears over multiple uses, these nuts can still be reused a few times, making them a more cost-effective and sustainable fastening solution compared to single-use thread-locking adhesives.

8. Standardized for Easy Integration

Manufactured to DIN 982 and ISO 7040 standards, A4-80 Nyloc nuts ensure precise dimensional accuracy and full compatibility with metric bolts and fasteners, allowing for seamless integration into various applications.

9. Environmentally Friendly and Maintenance-Free

Since stainless steel is 100% recyclable, these nuts contribute to sustainable engineering. Their low-maintenance design also reduces the need for frequent replacements, saving costs in the long run.

Conclusion

Nyloc nut DIN 982, ISO 7040, A4-80 offer a high-strength, corrosion-resistant, and vibration-proof fastening solution. Their nylon insert locking mechanism, extreme durability, and chemical resistance make them ideal for marine, offshore, heavy-duty industrial, and high-performance applications where reliability and long-term fastening security are critical.
