As epicfail48 suggested, the range from T5-T8 will cover you. I've liked Wiha for fit but if this is an occasional use tool no need to overspend on #######.
Thinking of those Wiha #######, I really like them. Unlike the .05" hex keys from a variety of makers that don't fit many of the fasteners well. Trying to match the driver to fastener and fastener spec is all over the place. Frustrating feeling.
Rambling off, at $.03-$.05 a fastener a wrench that cams out ruins them and for as much as folders are disassembled in the process, that cost adds up.
Good sharp well fitting tools, good spec fasteners, makes the process nice. Part of the game though we want to be efficient because this all adds up over the years. Same gripe with drill bits. Uh-oh I can get going there...
