6-32 is a course, ie nc, thread. 8-32 is a fine thread, ie nf. The fine
threads do less cutting relative to the screw's major diameter.
The 8-32 will be less likely to break than the 6-32 which, in steel, is
a consideration. In aluminum probably either one would free of worry.
Maybe the 8-32 would be a little freeer.

should use 6-32 or some less coarse thread like 8-32 would be better?

What's the application? The 8-32 would be a stronger bolt, with more
thread cross-section. But it may not be necessary for whatever you wish to
hold.

strength not an issue
