| I had a problem, found a 3mm tap in my box o'taps and fixed the bad one. Meanwhile, I had ordered a set of replacements.
It appears that the Align manufacturing folk are using the wrong kind of tap to thread the hole. A standard tap that starts out with a tapered end that eventually works its way up to the ful thread appears to be what they are using. Unfortunately, when you use one of these taps on the flybar collar, the tap cannot go deep enough to fully cut threads in the collar, as the tip of the tap runs into the opposite wall of the bore for the flybar, before the full thread cutting portion of the tap has done its job.
Take a new flybar control arm and simply try to turn the set screw into it, without having the flybar in place. The set screw is bound up just about the time the point protrudes through collar, as the threads in that region are not properly cut.
There are two solutions.
First, the Align folk should be using a bottoming tap -- one that allows you to cut full threads up to the end of the tap.
The other solution would be for them (or us) to drill the pilot hole for the tap clear through the collar. Doing so allows a standard tap to go further into the collar, and into the hole on the opposite side of the bore for the flybar. This allows the full thread cutting part of a standard tap to do what it needs to do all the way through the pilot hole.

barley tightened the screw.
