Adopting a horizontal steel structure and a freely movable worktable, it can be used for samples of various lengths.
Applications:
Suitable for testing the tensile and torsional performance of high lock nuts, the test content includes locking torque, breaking torque, pre tightening force, and loosening torque. It is also suitable for testing the locking performance ofself-locking nuts, achieving conventional locking torque tests and torque loading tests for self-locking nuts.Total friction parameter μ, thread friction parameter μ, end face friction coefficient μ, tightening coefficient K, and other parameter
