There ARE four M5 x 16mm long Self Tapping screws with Torx heads ( T3331414 )
used with washers on both halves of the Main Fairing, but not to hold the Fairing in place -
they appear to be for securing the side Duct to the Fairing.

World of Triumph / Trophy SE / RH Side Fairings. There are also four M6 x 12mm long Pan Head Torx Screws ( T3331042 )
shown in the Parts List for the Cooling system.
2 are used without washers to secure the Expansion Tank,
and 2 with washers securing the RH Bracket / Seal.

from World of Triumph's listing, but the parts can still be seen
as Item No. 29 in the exploded drawing here :
