In safety wiring, what does the term "double twist" refer to?

The term "double twist" in safety wiring specifically refers to a securing technique that involves twisting wire to secure fasteners. In safety wiring applications, two twists of the wire are made in between the components being secured. This creates a locking effect, ensuring that as vibration or movement occurs, the fasteners remain tight and do not loosen. This technique is vital in aviation maintenance, where the integrity of fasteners is critical for safety.

The focus of safety wiring is on preventing loosening, and the "double twist" achieves this by providing a strong and stable connection. It enhances the securing process by ensuring that the wire does not become loose on its own, thus preserving the integrity of the assembly.
