CAN BE USED REPEATEDLY:The hardness of the wire screw is higher than the screw, so it has little wear and tear in connection with screw, and can be used repeatedly EXCELLENT CONNECTION PERFORMANCE:Strengthen the connection strength and improve the connection condition, avoid sliding wire, tooth , and obtain excellent connection performance Because of a certain elastic, can make the load on the thread is more even, eliminate the screw and screw hole deviation between the pitch and tooth type, and can absorb vibration, thus increasing the screw thread connection strength and resnce to fatigue strength Strengthen the connection strength and improve the connection condition, avoid sliding wire, tooth , and obtain excellent connection performance Strengthen the connection strength and improve the connection condition, avoid sliding wire, tooth , and obtain excellent connection performance
