T-Nuts Don’t Fit
The T-Nuts don’t fit in the 80/20 channel, it’s not even close. The company is aware of this issue but hasn’t fixed the problem.

Tnuts Don't Fit
Like others have noted, the brackets and M8 bolts are fine, but the tnuts are too wide and don't fit my 4040.

poor QC, bad fitment.
Overall poor quality control. A number of the brackets had burrs. More troublesome, a significant number of the channel nuts were out of tolerance for the channel from 8020. Would not suggest this unless you want to buy double and toss 3/4.

Track nuts did not fit.
Pretty decent quality for the price. Good thing I had other hardware as the track nuts were to big to fit in my 4040.

Bolt heads too shallow
The hex bolt heads are about half as deep as others causing the key to slip out when trying to apply any torque above 5 pounds. Who would use this kind of quality?
