Makes sense now, good info! I’ll be using these for aftermarket wheels, so the regular acorn is what I’ll be going with.Acorn bulge it the wider seat on left, acorn is on right. Both have 60 degree conical seat. If you are buying for aftermarket wheels you probably want acorn, but for OEMs you want acorn bulge because the acorns concentrate the clamping force over too small a surface area.
I think Gorilla uses the term acorn bulge. Some other brands call it acorn flare I think. I think McGard is a great brand, I don’t care what brand you get.
