When I was working my firm made parts and subassemblies for aircraft, Harriers used BSF, Westland used UNF variants and metric, and Airbus used UNF and variants and metric on the same aircraft.

Variants of unified threads included UNEF and UNJEF which had slight changes in core rads to improve fatigue resistance in critical fasteners.
