When a fastener is spaced four to six inches from the next fastener, how many fasteners may be connected with a lockwire?

The correct answer indicates that three fasteners may be connected with lockwire when spaced four to six inches apart. This is in alignment with industry standards and practices regarding the use of lockwiring to secure fasteners against corrosion and vibration.

Lockwiring serves to prevent fasteners from loosening due to dynamic forces. When fasteners are properly spaced within the identified range, connecting them with lockwire creates a secure method of maintaining tightness. Generally, lockwiring is practiced to ensure that no more than three fasteners are connected to ensure adequate distribution and effectiveness of the lockwire in preventing rotation or loosening.

In contrast, connecting more than three fasteners with the same piece of lockwire could lead to complications, such as uneven tension distribution and difficulty in pulling the wire tightly. This may compromise the intended purpose of securing the fasteners effectively.
