clout nail

I'm a little stuck... Click here to teach me more about this clue!

'one hammered' is the definition.
I can't tell whether this defines the answer.

'local i nut drunkenly' is the wordplay.
'drunkenly' is an anagram indicator.
'local'+'i'+'nut'='localinut'
'localinut' anagrammed gives 'CLOUT-NAIL'.

'in' acts as a link.

Can you help me to learn more?
