Good fit 6mm nuts
Perfect performance with 6mm hex head bolts. Worked well with lock washers. Using for indoor/outdoor structures. Will monitor performance in high humidity levels and moisture environment. Not sure of the class or strength rating. The nuts were strong enough for fastening the structure using 10 mm socket without thread stripping. Very happy with these 6mm standard nuts. Will order again as needed.

What's nut to know?
I end up getting quite a few metric screws, but I never seem to pick up any nuts. So I ordered these and they are a great price for what I needed. Other hardware stores end up charging quite a bit and charge per nut, so it was a good buy for me.
