DIN985 M8 Self-locking Nuts

Its flange shape allowsfor easy installation and removal with standard tools. Whether you're securing pipes, assembling equipment, or building structures, this self-locking nut is an essential addition to your toolkit. Discover its many uses and experience the benefits of high-quality stainless steel hardware.

Designed for secure and reliable fastening in demanding environments, our DIN985 M8 Self-Locking Nuts  are precision-engineered to meet the highest industrial standards. Also known as prevailing torque nuts , these hexagonal nuts feature an integrated locking mechanism that resists loosening due to vibration and dynamic loads, ensuring long-term joint integrity without the need for additional locking devices. 
Manufactured in compliance with the DIN 985 standard , these nuts are dimensionally accurate and interchangeable with other metric fasteners, making them ideal for a wide range of mechanical and structural applications. 
Key Features: 
Size:  M8  
Thread Type:  Coarse Thread (Metric ISO Standard)  
Material:  High-quality stainless steel SS304 , offering excellent corrosion resistance and durability in both indoor and outdoor environments  
Strength Class:  A2-70 , indicating a minimum tensile strength of 700 MPa   
Finish:  Natural color (standard passivated finish for SS304)  
Standard Compliance:  DIN 985 , ensuring international compatibility and quality assurance
The self-locking function is achieved through a nylon insert or deformed thread (depending on manufacturing method), which creates friction between the nut and bolt to prevent unintended rotation. This makes DIN985 nuts particularly suitable for use in automotive, machinery, electrical equipment, transportation, and other industries where vibration resistance is crucial.
