At least for me, although as I read on some reviews some people had issues with these screws.
I bought them to replace the screws on a Licensed Floyd Rose tremolo made in Asia ( the guitar is a Maison ) and they don't stuck when I screw them all the way down, they have a rather good grip on the dial and they screw on securely without any play or being too tight.
The only difference is that they are a bit shorter than the original screws, but I tried Floyd Rose original screws and they were also shorter.
So, they may not fit all types of Floyd Rose trems out there, but I've got nothing to say about these screws, except that they were a good buy.
