Description
The high-strength bolt axial torque testing machine (also known as bolt torque and axial force tester, torque coefficient testing machine, or models like ToronBTT-5000, CYLSN-1000E, and HST-BW series) is a computer-controlled precision instrument that applies simultaneous axial tension and torsional torque to high-strength bolt assemblies for accurate performance evaluatio
