How does the number of twists per inch affect safety wire performance?

The number of twists per inch in safety wire plays a significant role in determining how effectively the wire secures fasteners against loosening due to vibration or movement. When more twists per inch are applied, the wire grips the fastener tighter and creates a more secure connection. This is because the increased number of twists distributes the load more evenly and enhances the friction against the surfaces being secured. As a result, safety wire with more twists demonstrates improved security, reducing the likelihood of mechanical failure in critical applications.

In contrast, fewer twists can lead to a looser grip, which may compromise the effectiveness of the safety wire. While some resilience is beneficial, a balance is necessary and no protective benefit comes from reducing the twists significantly. Therefore, maximizing twists while keeping them practical leads to better safety wire performance overall.
