This is interesting because I was wondering the same thing, but more for replacing the bolts.

Does anyone know the SPEC?

The IAC comes with two different styles...mainly because it puts a hose clip on one end of the bolt (top bolt close to hood)

I want to replace this one because the head is starting to strip...

Anyone have the spec, dia. etc?
