the main difference is that 7075 is a much harder aluminum. 6061 is a good balance of weldable and machinable. 7075 gives up on weldability and gains more strength. It machines like a quality steel (not hot rolled or 1018 cold rolled) as where 6061 machines like "aluminum" as soon as you put a tool/tap into the two materials the charicteristics (sp?) are night and day.
6061 will work, just make sure you have a coarse thread.
