[kikkegek]

hi guys,

since I am on the other side of the ocean I wanna order a assorti of nuts and bolts, so I have some spares when I am doing stuff to the car. everything is metric over here, so I need to special order these.

Now I have nu clue of what size and type I should order to have a nice collection on hand. Can you guys help me decide?

there are some shops over here selling them, but I see UNF and UNC and stuff and I am lost.

some advise would be very helpfull....
