I am using McFarlane push-pull cables for things like oil cooler shutter, cabin heat and (the question at hand) the alternate air door.

These cables have a fairly thick (I think it's .093") inner cable.

Stock instructions for attaching to the alternate air door have you wrapping the cable around the #8 screw and cinching down with a washer and nut.

The inner surface of the door has to be flat, obviously, which necessitates a flat-head screw (or equivalent).

Anybody have a better method for attaching the cable? The thick inner cable *is* bendable, but my tests end up with a relatively unattractive (although serviceable) loop of wire.

N.B. The whole alternate air door assembly is already built, so I'm not looking for alternative solutions to the door. Neither am I interested in *not* having an alternate air source. Just a different way of attaching the cable to the screw (or a different sort of "screw" to attach to).

I thought of drilling a hole in the screw itself...not sure if that's a viable option or not.

TIA...

Bug nut is the answer you are looking for.

Here is one example.

And which part is supposed to go on the inside of the door, which *must* be flush?

Without seeing your setup, kinda hard to answer.

You may have to attach a small piece of angle to the door, and use that as an attach point for the bug nut and cable.
