I have not used Tony's screws in quite a while, but the last time I checked his screws are stainless steel. grade 12.9 stainless steel? I don't think so. Stainless is graded on a different scale (18.8) or something like that, and like I stated previously stainless is inherently a softer material making it more prone to failure. It works great for certain large scale applications (in water) due to the fact that it will not rust or degrade like regular carbon steel will. It just will not give you the same strength and holding power either. Especially in such a small (3mm) application. Some people like having softer hardware so it is easier to remove if there is a problem. Plus it gives you that nice shiny look that appeals to others. I personally like building things to last, and resist breakage so I use the harder material. Personal preference.
