this is normal for a cheap tool...
and you may have damaged the BB spindle threads too.
the top hat is typically for use with a different spindle design... shimano octalink, or FSA Isis spindles... round, larger, and they use splines instead of a square taper...
if the hat's brim won't fit into the square part, the hat is definitely for the round splined spindles.
i used to put a small washer inside the square between the spindle and the puller's ram... that protected the spindle's internal threads...
my Park CCP-22 crank tool doesn't mess up the threads.
