Safety Wire instalaltion highlights, double twist method: 

1. The safety wire is installed so that, if the fastener has any tendency  to loosen, it will cause the safety wire to tighten.
2. The maximum span of safety wire (between tensions points) shall be 6″ (152mm).
3. The maximum length of safety wire to be used in a single application is 24″ (609mm).
4. The number of twists per inch (1 twist = 1/2 complete turn) depends upon wire diameter: 0.020″ to 0.025″ dia, 8-14 twists 0.032″ to 0.041″ dia., 6-11 twists; 0.051″ to 0.060″ dia., 4-9 twists.
5. The wire which is looped around the outside f the fastener must always be routed UNDER the wire protruding from the hole (so that the loop will stay down and not cause slack.) This often requires the direction of the wrap and twist of strands to REVERSE from run to run, or run to pigtail. 
6. Pigtail should be no more than 3/4″ long and have a minimum of four (4) twists. Ends should be cut and bent toward fastener to prevent snags.
