unbolted

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

'having opened' is the definition.
I can't judge whether this defines the answer.

'let out bound madly about' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'madly' indicates anagramming the letters.
'about' indicates putting letters inside.
'bound' with letters rearranged gives 'unbod'.
'let' anagrammed gives 'lte'.
'lte' going inside 'unbod' is 'UNBOLTED'.

'to' is the link.
