We sold out of pegs (6)
I believe the answer is:
dowels
'pegs' is the definition.
(I've seen this in another clue)
'we sold out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'we'+'sold'='wesold'
'wesold' is an anagram of 'DOWELS'.
'of' is the link.
(Other definitions for dowels that I've seen before include "Fasteners inserted into holes in two adjacent pieces to hold them together" , "Pegs for holding components together" .)
