Failure to put fastener on the ceiling? (5-2)

Ross

I believe the answer is:

screw-up

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

'fastener on the ceiling?' is the wordplay.
'fastener' becomes 'screw' (screw is a kind of fastener).
'on the ceiling?' becomes 'up'.
'screw'+'up'='SCREW-UP'

'to put' acts as a link.

(Another definition for screw-up that I've seen is " Disaster".)

I've seen this clue in The Telegraph.
