(OP)
Is it typical for stainless steel hex screws/bolts manufactured per ASME SA-193 to be passivateed? The standard does not specify performing passivation. Neither does ASTM A-962 referenced by this standard.

Does a Stainless Steel fastener thats been passivated, have the same chance that when torque is applied that threads end up 'galling' or does the passivate help in preventing that.
If so which surface treatment is the best at reducing this 'galling' affect?
