    I said copper nuts, but I think they could be brass- Never thought of that because the Dutch say copper for brass, but the real word is 'messing' or 'latoen',, oh dear, I'm confused again.
    If you want to use brass you should go for stainless studs. Stainless sheer during fastener removal is often due to galling bw SS nuts and SS studs (Like cold weld). You should not have that problem with brass nuts and you will be much closer together at galvanic potential chart. Get brass nuts that are taller than stock nuts to handle required torque.
    With regular carbon steel galvanic will attack thread studs more intensely since they are way appart on galvanic chart.
    Still titanium on titanium is your best bet...
