In the case of the second embodiment as well, the head of the threaded locking device 30 has the inner recess 2b of the downward recessed groove 2.
Even when the male screw 32 is formed so that there is a portion that is not screwed in between the pair of protrusions 2c when the male screw 32 hits the ceiling and is stopped, the lowest part of the lower end of the male screw 32 is just the pair of protrusions. The male screw 32 may be formed so as to be located on the upper surface of 2c.

Although not explicitly stated in the above description,
The male screw of the threaded locking tool in the hanger of the present invention is
It is preferable that the hanger bolt has the same rotation / movement direction as the rotation / movement direction (direction in which the screw advances). With such a configuration, even if a nut or the like for suspending the ceiling or equipment from the lower side is screwed into the hanger bolt, the threaded locking tool is pulled out from the downward recessed groove 2 or loosened. It is safe because it can prevent dripping.
