1. Shoulder Limit Structure, High Lateral Stiffness (Higher Vibration Reduction Capacity, Higher Stability)
2. Through nesting type structure design and self-locking structure design, the vibration reduction fastener realizes preassembly in factory, easy installation on-site and convenient operation，replacement and maintenance. The installation height of fastener system is basically the same as that of the ordinary ones, which simplifies the construction of rail-way system and the operation of transformation construction.
3. There are a variety of ways to realize the adjustment of distance and height functions of fastener systems , which could realize the demands of larger distance and height adjustment in the process of later operation and maintenance.
