Dynamic Wedge Thread Bolt:
Dynamic Wedge Thread Bolt is made by high tensile strength round steel, one end equipped a steel wedge, and bolt body has paddles to achieve dynamic support.
Advantages of Dynamic Wedge Thread Bolt :
1.Can resist, absorb and suspend energy from rock bursts.
2.Excellent control of squeezing rock areas.
3.High static support stiffness yet allows for significant ductility once the yield limit has been exceeded.
4.The paddles can act as mixers when used with resins.
5.If a portion of the bolt fails, the remaining section retains functionality.
