It is not recommended to continue using the shackle if there is any slight deformation. Even if the shackle looks fine as a whole and there are no internal injuries detected by the instrument, it is still recommended to replace it. Many people do not fully understand the reasons behind this. Let's analyze it below for everyone to understand.

First of all, we need to know that the components of a shackle are the buckle body and the transverse bolt. The closure locking of the shackle is achieved by the transverse bolt passing through the screw hole, and through continuous twisting, the thread is precisely locked to provide protection. The precision of production design for shackles is very high, and it is necessary to ensure the symmetry of the two screw hole positions to ensure the smooth passage of the horizontal bolt. If there is a slight deformation in the shackle, then the situation is different.

A slight deformation of the shackle can cause an imperceptible displacement of the screw hole position, which may not appear to be a major issue, but can make it difficult for the bolt and screw hole threads to achieve precise engagement, resulting in bolt slippage that cannot be repaired. So even a slight deformation of the shackle has a huge impact on its overall performance, so it is not recommended to continue using it when there is a slight deformation.
