What type of screw/bolt is this?

[conny]

That is a hex head button screw.
You need to measure the length, (from underneath the head to the bottom), and also measure the diameter across the bottom.
Assuming your hand is an average size, I would say that is 6mm diameter by 30-35mm long.
You then just need to look for them in Screwfix or Amazon. Though you won't get a single one. Usually packs of 5, 10 or many more.

I could have sworn that was mentioned earlier.

Yes. It was. Dunno by who, though

It might be a button-head screw

Someone said it might be. Someone else said it was. Can you see the difference?

Yep, hex button screw, needs an Allen key.

OK - I recorded a brief peak temperature of 28.9C here yesterday, I don't think it will become that warm today.

I think it is a hex-socket button headed screw

Yep, I think you may be correct in that assumption, and chrome vanadium.

Well, no one has mentioned the serrated flange yet!

 

[Old Salt]

Not chrome vanadium surely? 3 pages yet?

 

[RandomGrinch]

So, my belief is, judging dimensions compared to my fingers..

It is an M6x20mm (possibly 25mm), hex socket, button head screw, with serrations.

Surely zinc plated? ...more probably stainless

...and still not three pages!

Why would it need to be stainless?

It wouldn't need to be stainless, it is just every search result for anything close, is coming up with S/S.
