### ⭐⭐⭐⭐⭐ Good fit 6mm nuts
*by L***. on August 10, 2025*

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.
