Lock Nut

Name: Lock Nut
Brand: YONGYI

Product Introduction Anti-loosening nuts are special fastening and anti-loosening components for the automotive field, processed from high-quality base materials such as high-strength carbon steel and stainless steel, and can be used with bolts to achieve double fastening protection. The product integrates various anti-loosening structures such as nylon locking, all-metal locking and tooth surface locking. Based on the principles of thread engagement resistance, friction force or mechanical locking, it can effectively resist high-frequency vibration and bump impact during vehicle driving, and completely eliminate the hidden danger of nut loosening. With a complete range of specifications, it can be adapted to different types of automobile bolts. The surface is treated with anti-corrosion processes such as galvanizing, dacromet and passivation, which is wear-resistant and rust-resistant, meeting the stringent requirements for the long-term stable operation of automobile parts. Product Application Widely used in the fastening of key parts such as automobile chassis suspension, wheel hub bearings, engine compartment pipelines, gearbox casings and steering system tie rods. It is also suitable for automobile modification, maintenance and other scenarios, providing reliable anti-loosening fastening solutions for various models such as passenger cars, commercial vehicles and new energy vehicles, and is a core component to ensure the driving safety and stability of automobiles.
