...The wire Must to be Absolutely TIGHT. The 'Pigtails' are to be Bent-Back in-half, so the Next person does Not cut their fingers. It's the Correct Way and keeps the Pigtail from Unwinding under pressure.
NO less than 6-Turns/Windings on the Pigtail. On Aircraft, the Wire NEVER goes OVER the Bolt Head. If the Part is 'Bumped' during Installation, it Can Cut the Wire. The Stainless Steel wire, must be of a Diameter to fill at Least 70% of the Drill Hole. I have done these, where It could Only be Accomplished by Reaching Way-in with Two 'Needle-Nose' Pliers, one in each hand. Again the Wire Must be Tight!
