Compared with steel bolts, low torque is the main reason for restricting the widespread use of FRP bolts. The company developed high-torque FRP bolts by improving the structure of the bolt and optimizing the material design, which overcomes the low torque of traditional FRP bolts. The shortcomings can be pre-stressed by torque to improve the stability of the supporting structure.
