Missing screws for lazer ZX5

[jackeltrader]

Hi Guys - I am after a bit of help!
I lost a screw the other day that holds the front hub together (I think) and I am having mega trouble finding a replacement. I know it is 3mx8 but don't know the pitch of the thread - I spent nearly 20quid on a full spare set thinking this would sort the issue but the kit does not have any in it - just really fine thread screws. I have found loads of kits on US websites but can't wait another couple of weeks for them to arrive! Does anybody know where I can get some.... I have attached the exploded view so you can see what I mean!
Thanks Peeps!!
