You have to grind the threads off the last 2mm of those bolts for them to fit in the bores in the pads.Wish I knew (because I need the same info).
As an FYI, I ordered some bolts (for the pressure pads of the locking nut) from Diablo Tuning and they wouldn't actually fit through the pressure pads. They fit the threads of the locking nut just fine, but wouldn't go through the holes in the pads. Very frustrating (but DT was great about taking them back and refunding my $$).
They have stainless screws for original floyd rose tremolos. Plus their prices are 20-50x what you can get them for at Ace or McMaster-Carr.I don't know if they offer edge specific ones, but Floyd Upgrades is good for this kind of stuff too.
