Abstract A testing device for tension–shear combined load was processed, and mechanical properties tests were carried out under pure tension, pure shear, tension–shear combined load. The influence of tensile stress and bolt axis angle on the test results and the corresponding variation law were analyzed. The results show that the mechanical properties of titanium alloy bolts under the tensile and shear combined load are obviously lower than those under pure tensile load, with a maximum decrease of 40%.
