8 mm crochet hook
The short answer
A 8 mm hook is a US size L/11, UK 0, and 8mm in Japan. Buy by the millimetre number — it's printed on every hook and it means the same thing everywhere.
Chunky weight, rugs and baskets.

Yarn weights that suit this hook
1 standard yarn weight list 8 mm inside their recommended hook range. Expected single crochet gauge over 4 inches is shown as a range — the CYC figures assume a mid-range hook, so at 8 mm you will land toward the loose end. Swatch before you commit.
