Nkyjz-500e-1000e-1500e-2500e Computer Controlled High Strength Bolt Torque and Axial Torsion Testing Machine
I. Equipment Overview and Technical Parameters
1.1 Main Applications
This testing machine is designed and manufactured in compliance with the following standards:
EN 14399-2:2005 High-strength structural bolting assemblies for preloading - Part 2: Preload
ISO 14399-2
GB/T 16823.2-1997 General rules for tightening threaded fasteners
GB/T 50205 Code for construction quality acceptance of steel structures
NB/T 31082-2016 High-strength bolting assemblies for wind turbine tower flanges
GB/T 3098.1-2010 Mechanical properties of fasteners - Bolts, screws, and studs
GB 50205-2020 Standard for construction quality acceptance of steel structures.
It is used to test the fastening axial force, tightening torque, torque coefficient, and tightening angle of hexagonal head high-strength bolt assemblies (M10-M64). Results are displayed and printed automatically. After completing a set of tests, the machine automatically calculates the average axial force, average torque, average torque coefficient, standard deviation, and variation coefficient for N test samples.
