Fastener tensile and torsion testing machine

Functional use:

       The patented ETT-C series fastener tension and torsion testing machine is used for self-locking nut conventional locking moment test, moment loading test, axial force loading test and high locking nut locking moment test, loosening moment test, screwing moment test, pre-tightening moment test and loosening moment test。The testing machine can automatically unload the clamping force。
