Following my purchase from Speedy fasteners, I have to say that I'm disappointed.
Many bolts had small nicks on the head, I installed some and I noticed that when I tightened them, the allen key got stuck almost every time, that means that the head is distorted, the material is really soft. The highlight was that one bolt broke while screwing it (with anti seize paste), before I even tighten it!
Note that every bolt is handtighted, I'm extremely careful not to overtight aluminium bolts.
Overall, poor quality in my opinion, they were cheap though...
