Is there a tool to undo these knobs?

[Sorr]

I am sure there is a tool to undo the nuts on this TLA?

Yep - in the UK they're known as "nut drivers", and work a bit like a cross between a wrench and a screwdriver. Useful tool. I picked up a set of bits that works with my screwdriver, like this:

Generic hexagonal wrench might be too thick to get in there...

I generally use my leatherman or any kind of pliers to grab the nut.

Be gentle and you should be fine.

The standard ones are too thick

I hve nut driver that has been turned down in a lathe for this job, but you could probably achieve the same result using a file. Before that I used to use pointed pliers, but it is possible to damage the nuts because they are brass quite soft.

looks like sifam or selco knobs.

one of 2 common tools one should have but does not.

It's a nut driver for these and a collet tool for the smaller knobs. the collet tool can come in different sizes based on the collet size. I made a couple with a dremel and a flat screw driver. it's not proper but I have yet to have any issues there.

collet tool

the nut driver can be found at most hardware stores without issue, just need to know the size. FWIW I have used needle nose pliers in this aplication without major issue but I wouldn't do it on the regular as you can chew up the nut if your not careful.

You need a box spanner:

Could 'dremel' a tool for this from an old IKEA wrench. Takes five minutes.

You may want to try these...
They're actually very robust.

Abbey, What do you mean by 'these'?

Thanks for the link Abbey. I think you posted this over a year ago. I thought they were a very good idea but at the time they were out of stock everywhere. Now they are back in stock so I have ordered a set.

Rocket Sockets are really handy and don’t scuff up paint work where a nut driver might.

if you’re in the UK, you can get these from Fuzzdog Pedals
