Tighten up, maybe using a spanner? (7)

I believe the answer is:

abridge

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

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

'a spanner?' is the wordplay.
'spanner?' becomes 'bridge' (I've seen this before).
'a'+'bridge'='ABRIDGE'

'maybe using' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.

Can you help me to learn more?

(Other definitions for abridge that I've seen before include "Cut short" , "Concentrate" , "Big read (anag) - shorten text" , "Shorten for e.g. radio" , "Shorten (eg, text)" .)

I've seen this clue in The Telegraph.
