Next, the head 3 of the pin 1 is held in the tightening recess of the spanner 22 and rotated in the tightening direction until the lower surface of the head 12 of the bolt 11 comes into contact with the member 31. After that, when the bolt 11 is further tightened to a predetermined tightening torque, as shown in FIG.
is disconnected. By tightening the bolt 11 until the throttle portion 4 is cut in this manner, the bolt 11 is reliably tightened to a predetermined tightening torque, that is, a necessary and sufficient tightening torque. As a result, the bolt 11 does not come off, and the member 31 is securely fixed between the lower surface of the head portion 12 of the bolt 11 and the member 32. Further, by cutting the throttle portion 4, it is possible to prevent the bolt 11 from being subjected to an excessive tightening torque, thereby saving unnecessary labor.
can be prevented from being destroyed. After this, bolt 1
Remove the shank portion 2 of the pin 1 left in the head portion 12 of the pin 1. This removal is easily accomplished by hooking the notch 6 of the shank portion 2 with a predetermined means. Note that the bolt 11 can be easily removed by inserting a hexagonal wrench 21 or the like into the hexagonal hole 13 of the head portion 12 of the bolt 11 and rotating it in the opposite direction to the tightening direction.
