Bolt inside and strive to hide (5)
I believe the answer is:
rivet
'bolt' is the definition.
(I've seen this before)
'and strive to hide' is the wordplay.
'hide' says the answer is hidden in the clue.
'RIVET' can be found hidden inside 'and strive to'.
'inside' acts as a link.
(Other definitions for rivet that I've seen before include "Captivate" , "Fasten -- engross" , "Trevi (anag.)" , "Bolt in iron" , "Transfix" .)
