Conductively coated fastening systems for full size determinant assembly (FSDA)

An apparatus comprising a fastening system and a structural assembly, wherein:

• the structural assembly comprises:
• a first structural element made of an electrically conductive fiber reinforced plastic, the first structural element comprising a first hole having a first structural element sidewall;
• a second structural element, the second structural element comprising a second hole having a second structural element sidewall;
• and
• an electrically conductive gap filler applied to the first structural element sidewall of the first hole of the first structural element, wherein the electrically conductive gap filler defines a first hole sidewall of the first hole;
• wherein at least a portion of the first structural element sidewall and the second structural element sidewall do not align;
• and wherein
• the fastening system comprises:
• a fastener comprising a head and a shank extending from the head into the first hole and the second hole.
