Main Purpose:

This machine is designed based on the standardGB/T16823.3 'Test Methods for the Tightening of Threaded Fasteners', a new type of comprehensive testing machine for fasteners, mainly used for detecting the physical properties during the tightening process of large hexagon head bolts in steel structures. It can automatically calculate parameters such as thread friction coefficient, supporting surface friction torque, tightening torque, clamping force, and torque coefficient.

Standards Met:

GB/T16823.1 'Stress Section Area and Bearing Area of Threaded Fasteners'

GB/T16823.2 'General Principles for Tightening of Threaded Fasteners'

GB/T16823.3 'Torque - Clamping Force Test for Fasteners'
