tiepins

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

'drawer say holds fasteners' is the definition.
I can't judge whether this defines the answer.

'drawer say holds fasteners' is the wordplay.
'drawer say' becomes 'tie' (I can't explain this - if you can you should believe this answer much more).
'holds' means one lot of letters go next to another.
'fasteners' becomes 'pins' (pin is a kind of fastener).
'tie'+'pins'='TIEPINS'

Can you help me to learn more?
