Eyebolts should be stored in a smooth environment, and should not be stacked for too long in a humid environment. If the environment is too hot and humid, the surface will be oxidized to a certain extent, so it must be posted in a ventilated place. The thread of the bolt usually needs special protection, and it is protected with butter to prevent the thread from being oxidized. The threads won't fit into the nut. Generally speaking, the thread of the eyebolt is slightly smaller than the size of the nut. In actual operation, the external load of the eyebolts will cause vibration. In addition, due to the influence of temperature and temperature, the friction force will become very small, and the long wire will be loose and damaged. So in general, pay attention to the maintenance of eyebolts.
At each maintenance, check for newly replaced eyebolts and some newly replaced accessories. The key to the inspection is to put the eyebolt on the head, and we also need to strictly check the thread of the bolt. Each threaded portion shall be free from cracks or dents. We also need to check the shape of the eyebolt teeth for any changes. If the thread pitch of the bolt is abnormal, it cannot be used. Therefore, the maintenance of eyebolts is very important.
