Lockwire is used to secure together two or more parts with a wire that must be installed in such a manner that any tendency for a part to loosen will be counteracted by an additional tightening of the wire.

The common method of installing lockwire shall consist of two strands of the lock wire twisted together. This is called the “Double Twist” method. The single strand method of lock wiring may be used for some applications, such as in a closely spaced, closed geometrical pattern. (triangle, square, rectangle, circle)

When multiple groups are locked by either method, the maximum number in a group should be determined by the number of unites that can be lock wired by a 24inch length of wire.

It is important not to install lock wire in a manner that the wire may be subjected to chafing, fatigue through vibration, or additional tension other than the tension imposed on the wire to prevent loosening.
