M3 just refers to a nominal metric diameter of 3mm, but the length can vary. For example, an M3x20 bolt has a 20mm long shaft (excluding the head) that is 3mm in diameter. Hope that helps. :D

Be careful, If someone says you need a M3x5 for example and you go to a shop and ask for one you might well end up with the wrong head because there is pan head, round head, truss head, countersunk or flat head, oval or raised head, bugle head, cheese head, fillister head, flanged head. The last thing you want to do is get your flanged head muddled up with your bugle head. There are also numerous different tops other than slot and phillips. In my experience it's best to actually see which screw you require.

...and of course there are also different materials: brass, steel, galvanized steel, jelly, etc. Well, OK, not jelly. :D

And different temperatures: hot, cold, warm, slightly chilled, tepid ... choosing just the right temperature can be very tricky.
