Just realised my very worn set of allen keys has a pointless 7mm included. Looking at it, clearly never been used.
Does anyone have a bolt with a 7mm head? Does anyone else have tools that have never been used?
We used to buy sets of Allen bits at work that came with a 5.5mm bit. When the guys lost a few of the useful sizes (4, 5 ,6) they'd buy another set. We must have had a draw full of the 5.5mm ones.
In my own tools I must have hundreds of unused ones now. Hardly ever work on cars now and certainly not classics so all my imperial stuff.
I seem to remember struggling to find one for a car once upon a time. It was a Citroen or a fiat I think.
Car discs often need them, not much use for bikes though
7mm is handy for some car brake caliper sliders if you ever do your own brake pads.
Yup, brake calipers on a mondeo getting on for 20 years ago - for some reason having to go to Halfords to buy a single Allen key sticks in my mind!
Audi and Volvo brakes need a 7mm one too. Never used a 7mm anywhere else though.
Ive a volvo, but never done anything past light bulbs and screen wash!
"A bit of a five and a half" is slang at work for someone who's a tool & seldom useful.
I had to go and buy one a few months ago for some random job on the car. Ranted at that particular engineer for a while, I did.
The only thing I've ever used my 7mm allen key on is the one-key release on some old Campag C-Record cranks, like these [img]

And a neighbour borrowed it once for his car (as above).
Naturally, I had to get it specially because it wasn't supplied with the set I had...
7mm are fork clamp mounts on some old BMW motorbikes
They are strutt top bolts on PSA cars and many others.
They do calliper carrier bolts on many cars
More pointless tool would be them ****ing triple square bits found on vw. Different for the same of being different bollocks.

Actually I realyl like using those - more positive than torx or allen bolts. Once you buy a set, it's plain sailing 🙂
Surely by your own justification.
Once you buy a 7mm Allen key it's plain sailing.
I find it easier just not to buy a vw then I won't need triple square 🙂
I've got one...calliper bolts on a VW T5.
Yep, several things on my old Peugeot 106 GTi. Remember neither my huge car socket set or any of my bike tools had 7mm and I had to buy it separately.
