Lockwire diameter is specified for holes larger than which threshold?

• A. 0.032 inch
• B. 0.045 inch
• C. 0.062 inch
• D. 0.025 inch

Answer: (A)

Lockwire sizing is determined by the size of the hole it passes through. When the hole diameter is larger than a small, defined size, the maintenance data requires you to specify which lockwire diameter to use so the wire will fit properly and keep the fastener secure. That defined size is 0.032 inch; for holes bigger than this, you must document the appropriate lockwire diameter. Holes that are 0.032 inch or smaller typically don’t require selecting a lockwire size from the data because smaller, standard diameters cover those cases or lockwire isn’t required in the same way. So, the value 0.032 inch is the point at which lockwire diameter specification becomes necessary.
