Thanks for your feedback. No, the bolts and track were from different suppliers. So as you said, their definition of universal may be different. I did grind one down and it now fits perfectly.
Hello!
I just purchased 36” of T-track that’s supposed to accept any 1/4 - 20 t bolt. I also purchased a bag of 1/4 - 20 bolts. But for some reason the bolts don’t fit into the track. Am I missing something here? See pics
