8.8 grade steel bolts to wall mount a TV

TELLIT01

I've just bought a new TV and the user guide which comes with it state both the bolt type, and the maximum and minimum length.  Use anything other than the recommended at your own risk.  How do you plan to attach 40mm bolts to the TV.   40mm is roughly 1 1/2 inch diameter in old money.  That's probably larger diameter than the rivets in the Forth Rail Bridge.

I'm reading that 40mm is the length not diameter. 
I've no idea why people are thinking it's the diameter - just because op said M6 was a bit thin?

That is exactly right. I should have said its 40mm length bolts x m6

Just for future reference, bolt sizes are usually given diameter first, then length. So M6 X 40
Bolts have a plain, unthreaded part of the shank, set screws, sometimes called set pins or machine screws,  have a thread all along the shank from the head. 
It's worth knowing because it can save you ordering the wrong thing.

You're right.  One of the previous replies referred to 40mm diameter and I got caught by that.

....and that monster you refer to is the Forth Bridge, the next is the Forth Road Bridge and the next is something else!! (Just a crossing except when it's iced up!)

Riveting eh?

Sorry Tellit but do get things correct . Almost as bad is calling that puddle in Cumbria lake Windermere or that clock tower in that small Southern village Big Ben!

You just posted a link which expressly disagrees with you?! The bolts on that Halford link are number of x dia x length. As is standard practice.

Maybe it's the fact that it says "bolts" on the packaging but they are set screws.
