What is a double-layer locking washer？
It is a special gasket used to prevent bolts or nuts from loosening. It consists of two gaskets with toothed or wedge-shaped surfaces. Its working principle is to use two washers to lock each other, thereby enhancing the anti-loosening effect. It is particularly suitable for occasions that require high-strength anti-loosening.
The main uses of double-layer locking washers 25201 are:
Prevent bolt loosening: effectively prevent bolts and nuts from loosening under vibration, impact or heavy load conditions, such as connection points in mechanical equipment and building structures.
High vibration environment: suitable for high-vibration and high-impact working environments such as railways, wind power generation, and mining equipment to ensure that the connection parts remain stable during long-term use.
Mechanical equipment: widely used in the fastening parts of mechanical equipment, especially equipment that needs to be frequently operated or bear large loads. Such as elevator guide rail connections, motors, reducers, car fixing devices, etc.
Automotive industry: used in high-vibration and high-temperature parts such as automobile engines and transmission systems to prevent bolt loosening from affecting safety.
