Most of the aluminium extrusions I use for building mixers etc have tapped holes so they can be affixed to side plates. These are fine if you only want to use the standard length extrusions but if you need to cut the extrusion you need to tap the cut end so it can be affixed. However, I have several times come across extrusions that use self tapping screws instead of taps and machine screws. Now I always thought self tapping screws were really only meant for sheet metal and not for the half inch or so depth required to support an extrusion. Are self tapping screws a viable alternative for this application?
