Margaret's means of fixing things (4)
I believe the answer is:
pegs
'fixing things' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Perhaps you can see an association between them that I don't see?
'margaret's means' is the wordplay.
'margaret' becomes 'Peg' (nickname for someone called Margaret).
'means' becomes 's' (I can't explain this - if you can you should believe this answer much more).
'peg'+'s'='PEGS'
'of' is the link.
Can you help me to learn more?
(Other definitions for pegs that I've seen before include "Wooden pins" , "Washing line clips" .)
