A threaded member capable of detecting tension includes a sensor component. A receiving space is formed in the threaded member. The sensor component has a flexible member and a sensor. The sensor is disposed on the flexible member. The sensor component is disposed in the receiving space of the threaded member and preset in a compressed/flexed state in an axial/longitudinal direction of the threaded member. When an article is tightened with the threaded member, the threaded member is tensioned to change the flexion of the flexible member. At this time, the sensor can detect and find the tension of the threaded member to achieve the tightening force applied to the threaded member.
