I wouldn't say 8.8 is trash, ungraded is crappy stuff.The workers are super fast. The jigs they have are nice. Quick work like that with the driver is why I had a trashed screw on a Rlaarlo and I had to drill it out.
ok so 12.9 is good 10.9 is ok and 8.8 is trash.
Dose someone have a chart with info on it?
