Safety Wire Installation Using Double Twist Method with Milbar Pliers 
(AEROSPACE STANDARD AS567)

1. The safety wire is installed so if the fastener has any tendency to loosen, it will cause the safety wire to tighten.
2. The maximum span of the safety wire (between tension points) shall be 6" (152 mm).
3. The maximum length of safety wire to be used in a single application is 24" (609 mm).
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 of 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 the fastener to prevent snags.
