Try hard to get rivets out (6)
I believe the answer is:
strive
'try hard' is the definition.
(I've seen this in another clue)
'rivets out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'rivets' with letters rearranged gives 'STRIVE'.
'to get' acts as a link.
(Other definitions for strive that I've seen before include "Work hard - compete" , "Make every effort" , "Try hard, make an effort" , "Make great efforts" , "Building propped against the wall of another" .)
