How do I know what size nut goes on what size bolt?

If you can't work out that yourself, you shouldn't be let loose with a pack of bolts.

MickS - LOLraj... nor near a pack of condoms, either.

There is your answer M3 X 35 So you need an M3 nut to go with your M3 screw. It's a 3 millimeter thread (about an 1/8th") x 35mm long (inch and 3/8) at that small the pitch will be about .75mm.

Bring your bolt to the store and try it out. Surefire way.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
