100Pcs M6 x 1.0mm Nylon Insert Hex Lock Nuts Locknuts

Works as should. Mid height profile. Happy with them.

Arrived promptly and work perfectly. What more can you ask of your nuts?

Why did you pick this product vs others?: The per unit prices was so much better on Amazon.

Great fit and fast shipping. The black finish is a nice gloss finish.

These are good quality and the package is handy.

As expected

These M6 Lock Nuts fit the M6 bolts I had perfectly and the nylon prevents them from loosening exactly as described. As far as I can tell, all nuts are of consistent appearance and quality. These are great for applications where vibration or other factors might lead to the nuts loosening over time. The nuts are slightly more difficult to tighten than nuts without nylon, indicating that the nuts should stay in place well. Overall, these are exactly as described and work well.

I saw these and wanted to try them for my 1/10 scale RC cars. I thought their appearance of being a thin, "low profile" locknut would be perfect, as many traditional wheel nuts are huge, and/or have flanges that just don't look right, especially on a detailed, scale/replica build. These are in fact, perfect! They fit perfectly on M4 applications (most late model 1/10 on road RC cars) and, being smaller and thinner, they look a lot more scale. And, you get 120 pieces for $5.99 - You can't go wrong here. I've got ten RC cars, mostly 1/10 scale, and I seem to go through a lot of these. Highly recommended!
