Foster- Your sizes seem like they are for very small fasteners
Hex Key 5/64" is for a #2 Cap head
Hex Key 3/32" is for a #4 Cap head
11/32 Nut Driver is for a #8 Nut
If your team has standardized on one or two fastener sizes it makes it easier to carry less items, but the correct specialized tools for the job rather than a multi-tool.
Klein 68236 Fully Ratcheting and offset 3/8 & 7/16 Box wrench - Exact fit for Size 10 & 1/4 fasteners locking nuts that we have standardized on.
Klein or other Hex Key Folding Set - Make sure it has 7/64, 9/64, 5/32 and 3/16 to cover all standard cap heads #6-1/4 in size.
