NKYJZ-500E-1000E-1500E Computer Controlled High Strength Bolt Torque Axial Force Torsion Testing Machine
1.1 Main Applications
This sophisticated testing machine is expertly designed to evaluate the fastening axial force, tightening torque, torque coefficient, and tightening angle of hexagonal head high-strength bolt assemblies (M10-M39). It boasts automatic result display and printing capabilities. Upon completing a test set, it efficiently computes the average axial force, average torque, average torque coefficient, standard deviation, and variation coefficient for N test samples.
