Good quality lock nuts
I am new to metric nuts, and threads in general. I bought a machine that needed assembly, but there was a hole in the box, and it was missing 2 nuts. I guessed they were 7mm nuts, but when I went to the store, I bought 6,7 and 8mm nuts because I wasn't certain of the size. 7mm was too small, but the 8mm threads were too fine. I learned that 8mm-1.0 is fine thread and so I went to the store for 8mm-1.5 and the store only had one. It fit the threads, but the nut was defective and would install. So, I ordered these locking nuts, and they fit my threaded posts. In fact, they appear to be exactly the same nuts that came with the machine. Very happy to learn about metric fine and course threads, and that these nuts worked well.

True to their size
Did not fit what I wanted them to fit because I didn't measure, so that is MY fault. That said, these are their size. Truly a great quality nut, and I would buy them again.

Nylock nuts.
They threaded on and are holding up great. Buying hardware on amazon can be a crap shoot, but these were as advertised, and did the job.
