Head tubes aren't tapped. Steering tubes are threaded. The tube at the top of the fork. Schwinn is 24 tpi.
Yes I changed my answer. The website I relied on for my original answer was wrong.

Head tubes aren't tapped. Steering tubes are. The tube at the top of the fork. Schwinn is 28 tpi.

Should we be PC here? Tapping is treading a hole with threads and male threading is done with a die. But I guess you could tap a steertube if you really wanted to.

same threads as harley steering stems.

I think the fork tube is 24 TPI. The forged cranks are 28 TPI.Not sure what your doing but I had better luck fixing mashed threads with a thread file.A die wil cut fresh metal and the fasteners can fit sloppy afterwards.
