Of the 96 studs provided; one had no threads whatsoever and another six (6) of them went on partially (1/2 way) before the kock-nut stripped out on the stud causing the allen wrench to snap & go flying across the room! The six that would not go all the way on had to be cut from the track with a grinder.
Woody's tech service hotline told me; "each one is checked with a lazer, unless someone turned it off." They wanted me to send back the defective studs and the one missing threads and only after their inspection, promise to send replacments. My track now has 89 studs. Not 96 as required. There were a few leftover nuts but exactly the right amount of studs. Too bad they were not all perfect;-(
