Bolt that is attached to drive (5)
I believe the answer is:
scram
'bolt' is the definition.
(I've seen this before)
'that is attached to drive' is the wordplay.
'that is' becomes 'sc' (abbrv. for Latin scilicet; 'namely').
'attached to' is a charade indicator (letters next to each other).
'drive' becomes 'ram' ('ram' can be a synonym of 'drive').
'sc'+'ram'='SCRAM'
(Other definitions for scram that I've seen before include "on your bike!" , "Bolt" , "beat hasty retreat" , "Slangy order to go away, beat it" , "Leave quickly" .)
