[Walt Fricke]

What do you mean? One nice feature of the ARPs is that dome, and it faces "up", which is to say it is where the head nuts go. Because of the dome the washers drop right in, and so do the nuts. No fiddling around.

Alas, Henry's nice Supertecs don't have this feature, and ARP doesn't have the fine thread for the nuts. Couldn't put Supertechs in backward if you tried, though that wasn't the reason for the finer thread.
