You know you're in good company when everyone gets excited to talk about bolts!
Two things to add here:
-Course thread is recommended for tapped holes in cast iron, plastic too.
-The rule of thumb thread engagement is 1.5 (not 2.5 diameters), ie nuts.
That rule holds true for stainless screw into aluminum. 1.5D is plenty to ensure the head twists off before you strip anything.
