YSLR

YSLR nuts utilize the inherent elasticity of steel to achieve radial locking and forced locking. This product is relatively thin, making it suitable for situations where nut thickness is limited and other products cannot be used. Its simple design makes locking convenient. However, a drawback is that installation errors cannot guarantee the perpendicularity of the flat surface to the thread.
