Counting threads is not a complete alignment.
I DIY mine:
Park on a level spot. Garage floors might be ok, but driveways usually have a crown to shed water.
Get a 18" long laser level, stick it on your front tire bulges at 4 and 8 oclock positions. Aim the laser at the rear tires. You want the laser to just barely miss, to miss the rear tire by about 1/2 an inch. This gives you the tiniest amount of toe-in and accounts for the gap between the laser head and the front tire bulge the tool is resting on.
Adjust tie rods to suit. Once "done", drive forward and back ten feet and stop using only the e-brake. Check again, as bushings tend to settle. Then back the car out and park it facing the other way, in case you've got a crown in your parking space you didn't know about.
Incidentally, the other bubble in your bubble level can check camber. I like having the top of the tires 1/8-1/4 inch closer together than the bottoms, so a tiny gap up top should make the bubble level. Adjusting this is a higher level of complication; if you're not having pull issues leave it be and just set the toe.
