Special treatment methods for disassembly screw holes

If we only observe through the external structure, both D-shaped and bow shaped shackles belong to a symmetrical structure. However, if we pay attention to some details, we will find that the shackles are not symmetrical either, and their different treatments mainly occur in the screw hole part.

Not all of the two holes of the shackle have been threaded. There is only one threaded hole, which is the screw hole used for locking the cross bolt. This means that the installation of the cross bolt has a direction, and everyone needs to pay special attention to this. The correct way to cross is for the bolt to first pass through the non threaded hole and then enter the threaded hole, so as to seal the opening of the shackle. If installed in reverse, it will not have any sealing effect.

This is the detailed treatment of the shackle, and it is also the key to ensuring the normal use of the shackle. If you want to learn more about the treatment process of the shackle details, we can answer your questions at any time.
