If you refer to a "8mm" bolt, are you talking about a bolt with an 8mm head, or a bolt with an 8mm thread? M8 refers, unambiguously, to the thread size. (Well, apart from the thread pitch...)

If you think primarily in terms of 8mm, you might be thinking of the hex head size, which is usually M5 thread - and you might go and do something daft like buy threaded studding off fleaBay that's 3mm bigger than you really want, so will require _yet_ more back-figuring to try to get a half-arsed bodge to fit rather than admit you've cocked up...

But that'd just be silly, wouldn't it? And you're not silly, are you, James?

what size is the pipe, is it 6mm, and where can i get the correct sleaving for the pipe, / a alternative good job
ive searched and not had much success (dont really know what to search for, wording etc)

so, making it simple,
the 8mm nut there will go on that thread m8?

No.

ok ta

so what m is the rod

I found a Xsara HDi circa 2000 did the trick. Higher amperage, fits in the tray and the terminals are the right way round

Didn't you fit a tow bar to your car.l I reckon it would be easier to buy http://shop.ebay.co.uk/?_from=R40&_trks ... Categories

from Ebay, fit it with the new battery you have and install a battery charger in the boot to charge your old battery as you go along.

maybe this bigger battery may sort my problem with the charging my phone out

only one way to find out

250 brilliant!

There's a somewhat less than subtle hint in my post at the top of this page...

oh shit sorry, i only read the first bit, i had to google the word unambiguiusly and then didnt read the rest
sorry
is shall get my rear end down homebase and see what i can do

simplest way to think of it as what size hole will it go through?

M8 goes through a 8mm hole, M7 - 7mm, M6 - 6mm etc
the clue is in the name
