What might happen if the collar is not fully tightened?

When a collar is not fully tightened, it can lead to multiple issues that compromise the integrity of the assembly. An inadequately tightened collar might result in ineffective installation, meaning that the components it is meant to secure may not be held firmly in place. This can affect the overall functionality and safety of the assembled parts, creating potential risks in operations such as vibrations or misalignments that could lead to failures.

Additionally, if the collar is not fully secured, there is a greater chance that it may become loose over time due to operational stresses, movement, or vibrations. A loose collar can exacerbate the risk of failure by allowing the components to shift or become dislodged, which can create further complications.

Therefore, both the potential ineffectiveness of the installation and the risk of the collar becoming loose are significant concerns that highlight the need for proper tightening to ensure a safe and reliable assembly.
