You'll see the T5 marking when shopping for screwdrivers. The actual size of the screw's head is a function of the drive size and the head's geometry. E.g., if we look at page 14 of the EJOT DELTA PT catalog [1], we get head diameters for T5 from 3.0 (WN 5452) to 3.6 (WN 5451). Note that this page contains one table, not multiple individual tables: the dark-grey table on top shows the thread size that goes with the respective drive in the head-specific sections below. E.g., T5 corresponds to M1.6 [2] in this case.
