What size is the large bolt for Logitech shifter

[Baldbloke]

Hi,
I have a Logitech shifter.
It should have 2 desk clamps and a big single securing bolt.

Mine is missing the large single bolt. I want to replace it.

I've seen them advertised on ebay for anywhere between £12 and £25. D'uh?
It's just a bolt. I'm not paying those ridiculous prices for something I could probably buy from my local hardware shop for possibly just pennies.

Any idea what thread size I should be looking for, please?

Many thanks.
