All-Metal Hex Nut Self-Locking Industrial Fastener

The all-metal hexagonal anti-loosening nut is a fastener specially designed for scenarios with high vibration and high reliability requirements. It adopts an all-metal structure and forms a self-locking mechanism through built-in metal inserts, significantly enhancing the friction between the threads. This can effectively prevent self-loosening under vibration and shock conditions, ensuring the long-term stability of the connection.   The materials include ** steel and stainless steel **, and the surface can be treated with galvanization or nickel plating, which not only meets the corrosion resistance requirements of different working conditions but also can adapt to high-temperature environments (avoiding the high-temperature failure problem of plastic insert type anti-loosening nuts). The product has a rich range of strength grades, including class 4.8, 8.8, grade 2, 5 and many others, which can meet the diverse fastening requirements from general industrial to high-strength equipme…
