question about speedbleeders

[auh]

I was looking around this board because I want to put speedbleeders on my bike. It seems from what I found that every bleeder screw on the RC is the same, however when I was flushing my clutch the other day, the bleeder screw used a bigger wrench than the brakes did. Is it possible they can still have the same threading but have a different size head?

I don't want to order the wrong part number, but this is something I really wanna do because I broke my vacuum pump.

The part number I found that I think is the right one is SB8125L

if i remember the speeds have the same threads but use larger wrench
