The tan set doesn't appear to have any with hex heads, so they's probably be quite useless for many IFs.
Edit: Maybe they do have hex shafts, but the reviews really suck.
The reviews are not very good for either set.
I'd keep my eyes out for a good set of vintage Waldom-GC alignment tools like these on ebay.
