What is the name for words without vowels?

The only related term I have been able to find is:

consonantal - of, pertaining or including consonsants. (This definition does NOT however specifically exclude the use of vowels). To do so, I'd suggest adding "-only", i.e., consonantal-only Words.

For me, it's simpler to say "consonant-only Words".

BTW, The antonym for consonatal is vocalic (of/pertaining to vowels).
