Stainless Steel Nyloc Nut DIN 985 ISO 10511 Nylon Lock A2-70 Prevailing Torque Type Hexagon Thin Nuts with Nonmetallic Insert 304 Fine Thread

Description

The stainless steel nyloc nut (DIN 985, ISO 10511, A2-70) with a fine thread provide a secure and reliable fastening solution with enhanced resistance to loosening due to vibration. These prevailing torque hexagon thin nuts feature a nonmetallic nylon insert, making them ideal for precision applications requiring a firm, long-lasting grip. Ever Hardware provides custom made fasteners and customizable packaging.

1. Secure Locking Mechanism

The nylon insert inside the nut increases friction against the bolt threads, preventing accidental loosening from vibration, shocks, or rotational forces. This makes them highly suitable for automotive, aerospace, and mechanical applications.

2. Fine Thread for Higher Holding Strength

Fine threads have a higher number of threads per unit length, providing:
• Greater tensile strength than coarse threads, making them ideal for high-load applications.
• Better resistance to loosening, as the increased contact area between the nut and bolt creates stronger frictional forces.
• More precise adjustment, making them suitable for instrumentation, machinery, and applications requiring accuracy.

3. Thin, Space-Saving Design

DIN 985 nuts are thinner than standard Nyloc nuts, allowing them to fit in tight spaces where a regular nut might be too bulky. This makes them useful for electronics, compact mechanical systems, and precision equipment.

4. Corrosion and Rust Resistance

Made from A2-70 stainless steel (304), these nuts offer good resistance to rust and oxidation, making them ideal for outdoor, marine, and industrial environments where exposure to moisture or chemicals is common.

5. No Need for Additional Locking Devices

Since the nylon insert prevents self-loosening, these nuts eliminate the need for lock washers, thread-locking adhesives, or additional locking mechanisms, reducing both installation time and maintenance costs.

6. Vibration and Shock Absorption

The nylon insert helps absorb vibrations and shocks, preventing the nut from backing off in high-speed or high-impact environments, such as engines, turbines, and railway components.

7. Reusability with Proper Handling

While the nylon insert wears out over multiple uses, the nut can still be reused a few times, making it a cost-effective and sustainable fastening solution compared to one-time-use thread-locking adhesives.

8. Compatibility and Easy Installation

Manufactured to DIN 985 and ISO 10511 standards, these nuts are dimensionally precise and fully compatible with metric fine-thread bolts and screws, ensuring easy integration into various mechanical assemblies.

9. Suitable for Moderate Temperature Applications

The nylon insert remains effective in moderate temperatures, allowing these nuts to be used in a wide range of industrial, mechanical, and structural applications.

Conclusion

Stainless steel Nyloc nuts (DIN 985, ISO 10511, A2-70, Fine Thread) offer a secure, vibration-resistant, and corrosion-resistant fastening solution. Their fine-thread design provides stronger clamping force and precision, while the thin profile allows for space-efficient applications. These nuts are widely used in automotive, aerospace, machinery, instrumentation, and precision engineering industries where secure and durable fastening is essential.
