Replaced bolts as ordered for dancers (5,2,6)

I believe the answer is:

corps de ballet

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

'dancers' is the definition.
(I've seen this before)

'replaced bolts as ordered' is the wordplay.
'replaced bolts' anagrams to 'CORPS DE BALLET'.
But, I'm unsure how the anagram is indicated.

'for' acts as a link.

Can you help me to learn more?

(Other definitions for corps de ballet that I've seen before include "dancers" , "dance troupe" , "Dancing troupe" .)

I've seen this clue in The Daily Express.
