Computer Controlled High Strength Bolt Torque Axial Force Torsion Testing Machine



YJZ1000E Bolt Testing Machine
The main purpose is to test the axial force, torque, and torque coefficient of large hexagon head high-strength bolt assemblies (M10-M39). The instrument displays and prints the results. When the axial force reaches the standard value, the instrument will emit a beep and record the peak value. After holding for one second, it will automatically reverse to release the sample. The instrument automatically calculates and displays the torque coefficient based on the detected axial force and torque.
