  • Fastener friction coefficient tester

    Wantest new generation ett-b series fastener friction coefficient testing machine is used to test the total torque, end face torque, thread torque, total friction coefficient, end friction coefficient and thread friction coefficient of bolts and nuts. It can automatically measure tightening torque, thread torque, bearing surface torque, tightening axial force, torque coefficient K, total friction coefficient μ tot, thread friction coefficient μ th, bearing surface friction coefficient The friction coefficient μ B and other mechanical properties of bolts and nuts.

  • Fastener friction coefficient tester

    Ett-b series fastener friction coefficient testing machine is a new generation of bolt and nut friction coefficient test system independently developed by wantest. It is used for testing the total torque, end face torque, thread torque, total friction coefficient, end face friction coefficient and thread friction coefficient of bolts and nuts, which can meet the general tightening rules and fasteners of threaded fasteners The mechanical properties of bolts and nuts such as tightening torque, thread torque, bearing surface torque, tightening axial force, torque coefficient K, total friction coefficient μ tot, thread friction coefficient μ th and bearing surface friction coefficient μ B can be measured automatically.
