What happens if the safety wire is not properly installed?

When safety wire is not properly installed, one significant risk is that the bolts may loosen. The primary purpose of safety wire is to prevent fasteners—like bolts or nuts—from vibrating loose during operation, especially in environments with high mechanical stress or vibration. When safety wire is properly in place, it creates a mechanical bond that keeps these components secure. If the wire is not installed correctly or is omitted altogether, the fasteners may not maintain their intended tightness. This can lead to a cascade of failures, as loosened bolts can impact the structural integrity and functionality of mechanical assemblies, potentially causing malfunctions or failures.

The other possible outcomes, such as fraying of the wires, becoming too tight, or having no impact at all, do not accurately address the critical function of safety wire, which is primarily to secure fasteners against loosening. Safety wire must be correctly installed to ensure it serves its protective role, reinforcing the importance of proper installation techniques in mechanical applications.
