Self Tapping screws on tapped maker slide

I got my upgrade kit delivered today(wooohooo).

There is one thing that I’m not quite clear on in the instructions.

My original kit came with the self tapping screws before inventables changed to tapping the maker slide.

I remember around the time when I built it that there was some discussion that tapping the makerslide yourself could cause the self tapping screws to destroy the hole.

Can someone confirm if I should use the same screws that I took out as per the instructions or if I should get some new screws(if so what sort are now needed)

Thanks

I asked and this is the reply I got so I got new screws…
