Fixer in Sinai lauded (4)

I believe the answer is:

nail

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

'fixer' is the definition.
Both the answer and definition are singular nouns.
Maybe you can see an association between them that I don't see?

'in sinai lauded' is the wordplay.
'in' indicates a hidden word.
'NAIL' is hidden in the letters of 'sinai lauded'.

Can you help me to learn more?

(Other definitions for nail that I've seen before include "'For want of a . . . . the shoe was lost'" , "Carpentry fastener" , "Fixing device" , "Apprehend" , "Brad or tack" .)
