Bolted joint inner thread coating and methods of manufacturing

A method, comprising:

• applying a first coating material on a threaded region of an opening in a first multi-piece assembly included in plurality of multi-piece assemblies;
• inserting at least one fastener to the threaded region, the fastener including a mating thread selectively secured to the threaded region of the opening to create a first friction interface between the fastener and the first multi-piece assembly, the fastener having a second coating material;
• tensioning the fastener between a load surface of the multi-piece assembly and a mating thread of the fastener to define a second friction interface between the multi-piece assembly and the fastener, the second friction interface being spaced away from the threaded region such that the first coating material does not influence the second friction interface;
• adjusting an amount of the first coating material applied to the threaded region in a subsequent multi-piece assembly, thereby increasing friction at the first friction interface of the subsequent multi-piece assembly compared with the first multi-piece assembly, the friction at the second friction interfaces of the first multi-piece assembly and the subsequent multi-piece assembly being substantially equal.
