新型等强度螺纹钢锚杆是通过对轧钢机的轧辊和传动系统等工艺改造后由轧钢机直接轧制成的自身带有梯形牙扣的新型锚杆。主要优点是不用再加工和热处理、本身属等强度型，井下安装操作方便。
The new isochronous rebar bolt is a new type of anchor rod with a trapezoidal buckle, which is directly rolled by a rolling mill through the transformation of the rolling mill and the transmission system of the rolling mill.
