NDW-20000 is a new type of comprehensive testing machine for fasteners designed by our company based on the standard GB/T16823.3 "Test Methods for the Tightening of Threaded Fasteners" [ISO16047 Fasteners-Torque/clamp force testing]. It is mainly used for detecting the physical properties during the tightening process of large hexagon head bolts in steel structures, and can automatically calculate parameters such as the coefficient of friction between threads, bearing surface friction torque, tightening torque, clamp force, and torque coefficient.
The LLG-24HY anti-slip coefficient testing instrument is mainly suitable for testing the anti-slip coefficient of friction surfaces in high-strength bolt connections of grade 10.9 and 8.8, as well as in high-strength large hexagon head bolt connections and torsional shear type high-strength bolt connections (a special wrench for torsional shear needs to be specially ordered), testing, and research.
