10mm Allen key fitting?

Postby keyboardmonkey » 21 Aug 2017, 4:48pm

I bought a set of 'hex wrenches' that started at 2mm and went up to 10mm. After I had been faffing about for ages in the shop the bloke behind the counter - probably just to get rid of me - offered to sell me the set without the 10mm socket that I mentioned I probably didn't have a use for.

Eventually, I did get the 10mm jobby (in part because it left the holder looking like a smile with a missing tooth), but it left me curious: who uses a 10mm Allen key on their bikes? Or anywhere else?

I may just be imagining it, but aren't some crank bolts 10mm?

My Shimano Octalink cranks are 10mm, so is my Deore freehub.

shimano freehub body (for hubs with a steel axle) uses a hollow bolt that can be worked with a 10mm allen key . There is a 'better tool' for this bolt which is a spline bit, but a 10mm key works well enough.

Some kickstands are fitted with an Allen key bolt that uses a 10mm key too.

cheers

Although I can't ever remember using them I have a couple of old freewheel block remover tools that have a 10mm hex hole in them, as well as external flats for a spanner.

The 10mm hex also makes a good paperweight to hold down the workshop job ticket sheet if the window is open in the shop :lol:

My XT pedals use a 10mm hex key (no spanner flats).

I'm sure my VAR set has a 10mm allen key. After many years of stirling non-service I'm sure I found something I needed to use it for on the bikes :D , damned if I can remember what it was :oops: .

On closer inspection it's actually 8mm! Which is the largest size in my Teng set.

Cheers, folks. Tinkering with a freehub is a job I've managed to swerve. So far. I'd read that some MTB pedals took an 8mm tool. Mine are 6mm. A couple of my bikes use 8mm for the cranks. The 10mm will indeed make a splendid paperweight. Thanks for the tip :)

Campagnolo Ultra Torque cranks? But needs to be long to get there.
It is by riding a bicycle that you learn the contours of a country best,
since you have to sweat up the hills and coast down them.
Thus you remember them as they actually are...
