I have some "very finely-threaded" screws with flat endings and some un-threaded aluminum "bar" (2mm thick). I wish to have that "bar" threaded according to the screws, but since they are not self-tapping, I can't directly (I tried, and just managed to eat away the aluminum).
I have a couple of questions:
- Can I thread (tap?) aluminum using a self-tapping screw, just like you would with wood?
- If so, can I do it with threads of differing "fineness" (number of revolutions per mm along the shaft)? I find it very unlikely I'll be able to find the right ones.
Please excuse me if I have used any wrong terminology, English is not my primary language. Corrections are very welcome!
