The threads on these T-bolts are clean and the nuts spin on without any wobble, which is exactly what I needed for the RACKandROLL system. Four in a pack means I've got spares on hand for the next time one wears out.

Swapped these onto my trailer rack after the originals got stripped, and the threads caught cleanly on the first try. Getting four in the pack means I've got spares sitting in the toolbox for next time.

Swapped out two rusted bolts on my RACKandROLL setup and these fit the threads just right. The 4-pack is handy since I've got spares now, though I wish the nuts were a touch beefier.
