NKYJZ-500E-1000E-1500E Computer Controlled High Strength Bolt Torque Axial Force Torsion Testing Machine
1.1 Main Applications
This cutting-edge equipment is meticulously engineered to assess the fastening axial force, tightening torque, torque coefficient, and tightening angle for hexagonal head high-strength bolt assemblies (spanning sizes M10-M39). Unleash precision with results that are instantly displayed and printed. Once a test series is completed, the machine seamlessly computes the average axial force, average torque, average torque coefficient, standard deviation, and variation coefficient across N test samples, ensuring unparalleled reliability in data.
