Can you drill out the setscrew and clean up burred faucet threads with a
small triangular file?

At least on mine it was easier to use a fine saw to notch the backflow
preventer on either side of the setscrew and then break out the screw.
The body is brass and not very strong, the screws are relatively hard.

You caught me. Drilling out a small screw freehand without ruining the
threaded hole is a challenging test of skill. I've messed up enough that
when I needed to drill out broken screws on my lathe and truck's intake
manifold I made drill guide jigs.

Wasn't my idea, found it on the Web somewhere, maybe YouTube. Didn't
care about the backflow preventer, but did value the hose bibb.

Good link. Never paid attention to the distinction between jigs and
fixtures before this...
