Are locking wires effective
against bolt loosening?
Locking wire, also known as safety wire or wire lock, is a mechanical locking method. It is imperative that the wire is installed so that tension in the wire only allows the bolt head/nut to turn in the direction of tightening. The tension of each section of the wire must also be locked in place so as not to be affected by the accidental loosening of another bolt head/nut in the series.
Although this method provides reasonable loosening resistance, it is time-consuming to assemble and the bolt head/nut must be drilled to create the holes for the locking wire - increasing the cost again. The only way to remove the locking wire/safety wire is to cut it away – meaning that it cannot be reused and a new piece must be installed every time the bolted joint is maintained.
