I want to flush mount female panelmates for hurricane panel installation (in concrete block / stucco), but am not sure how to set the PMD-1 combo drill bit.

Does it go link this, with a countersink for just the top of the hex head:

Or like this, with a countersink for the entire non-threaded portion:

In the first case, I wonder if I'd have trouble driving the head all the way in. in the second case, it seems the non-threaded portion below the hex head would be loose, since the countersink is larger that it is.

Anyone know how this goes? There really doesn't seem to be any specifics out there, Elco seems to assume that you just know this kind of thing, but I don't do this sort of thing professionally. Just trying to get my own house prepared.

Thanks for the help!
