  • Work as expected
Size: ‎M5 x 0.8mm (50 PCS)
They go onto the matching screws smoothly. The nylon inserts provide the expected amount of friction. I did not find any malformed ones so far.

  • the smallest 3 sizes are too small for nylon of this type
Size: Lock Nuts Assortment Kit
I am surprised by how small these nuts are. I should have checked first. but I do not know how i could even use a nut this small with large nylon on one side. There is definitely no need to fill the container with the small sizes. I have not used them as they just arrived so I will update when I need them. one thing I know is that the only time I have needed M3 or M4 bolts, the nuts were built in. These are just too small to assemble without tweezers. ... show more
