DIN 985 Stainless Steel Lock Nut China Factory and Leading Suppliers
The DIN 985 Stainless Steel Lock Nut is a high-precision fastening solution engineered for critical applications where stability and security are paramount. Manufactured from premium 304 stainless steel, these self-locking nuts are specifically designed to resist loosening under extreme conditions, ensuring structural integrity in demanding industrial environments.
Integrating a specialized nylon insert, the DIN 985 nut utilizes the adsorption force and elastic resilience of the polymer ring to create a powerful friction lock against the bolt threads. This mechanism makes it an indispensable component for high-vibration machinery, automotive systems, and rail transportation, providing a reliable safeguard against mechanical failure.

Unlike standard nuts, DIN 985 features a nylon insert that creates friction against the bolt thread, preventing the nut from loosening due to vibration or torque.
Yes, 304 stainless steel provides excellent corrosion resistance, making it highly suitable for outdoor environments and moderately corrosive atmospheres.
Nylon has temperature limits. For applications exceeding these limits or reaching up to 300°C, we recommend our all-metal lock nut variants.
They are widely used in automotive engineering, rail transportation, aerospace, and heavy machinery manufacturing where vibration control is critical.
While reusable, the locking effectiveness of the nylon insert may decrease over time. For critical safety components, replacement is recommended after several uses.
Yes, our products are manufactured strictly according to the DIN 985 German standard, ensuring global compatibility and high thread precision.
