yes i know, i was more or like meaning the same, making sure nobody is  
really using expensive half sizes.
I reckon for aluminum the US screws would be better anyway, 'cause they  
have a coarser thread, and a sharper angle while metric screws have a 90  
degree angle i think. Not ideal for soft aluminum (but does work), i guess  
they are optimized for same material nut/screw max. pullout strength.
