Strange bolts

In our impression, the bolt is usually screwed in one direction, and it can penetrate the wall and board with only a little torque.

 
But the bolt I want to share with you today is a bit special. This is the two-way bolt. When we insert two nuts into the bolt, the nut will move towards the bottom in two different directions, which means that the bolt can rotate clockwise or counterclockwise.

 
So the question is, what are the advantages of this bolt? Of course, it is for better fixation. Due to the change of the working environment, the expansion or contraction of the bolt material will cause the bolt to loosen, and this two-way bolt can just prevent the nut from loosening. After one nut is screwed on, the other nut is screwed on in the opposite direction, so no matter how much force is used, they can not be screwed on at the same time.

 
Not only that, two-way bolts also have this kind of zigzag thread. When the nut is put on, it will continue to move to the left and right towards the bottom, and this kind of labyrinth thread, although it is very difficult to put it in.

 
But when you take it out, you just need to follow the straight line. What other special bolts do you know
