Allen wrench size?

[slsl60]

I have two no-name bathroom faucet (centerset, one handle)--one is dripping and the other leaks from the base when on full cold. I assume it's either the cartridge or the seals so I'll have to take them apart. What size Allen wrench would I need? It's looks like a Moen (which uses 7/64) but it's not a Moen (unless it's a builder's brand made by them).

I’m not sure of the size but it’s SAE and it’s on every small set of Hex keys.

If you say it's a no name,how are you gonna fix if there's no name ,just replace them both,that way,your not wasting time looking for parts,and you know what's installed

Looks like a Moen to me.
