now you got me wondering if my snap on set has one in it?
Yeah Snap-on put the 7mm in both 3/8 & 1/2 drives sets

Vauxhalls use a 7mm bolt also on brake calipers. I was working onsome kneeding rollers at work and needed a 14mm hex key, ordered one from RS at 5pm got it the next day straight from Facom in France didn't even know they went that large
for what it's worth, I have a companion (CHEAP craftsman brand) set of 3/8" drive allens. Cost like $10 or so, been using them for years for brakes, no problems yet. Just a thought.
You can def tell the are cheap, but if you don't use it every single day, it will do fine.
The come in torx, MM and SAE, so for about $30 you could have the whole shebang,

I have noticed in recent years that I am using hex keys also known as Allen keys, more often, in fact daily,
I have a few large sets of each size key, metric and imperial, also, long arm, short arm and My favorite ball hex, I only use two brands, and they have lasted well, DRAPER and US made UNBRAKO, also have a full set of hex sockets and a full set of extra long hex sockets all 1/2 or 3/8 drive,
I have found that some standard size hex sockets are sometimes not long enough to reach the cap head,
The cap head is a very popular fixing by car manufacturers, and every European made vehicle will have them on, in fact I've seen them common 7mm and 9mm on brake calipers, also a lot now on suspension, and anything in the engine bay,
How the world changes,
As I am now in the tools and fixings trade, (formal mechanic for over 20 years ) I can see how the industry has changed, The automotive industry world wide use 70% socket caps, 10% torx or security torx, and now only 20% hex head bolts, and out of the 20%, 17% is metric,
I still have a full set of whitworth sockets and spanners, and Imperial, and AF, Full sets of each, which I have not used for years and years, all metric, may be the odd AF comes out to play if I'm lucky,
