#4-40 Nylon Insert Lock Nuts by Bolturos

These nuts are made of high-quality 18-8 stainless steel for corrosion resistance. The nylon insert grips the screw to prevent loosening from moderate vibration without damaging threads. Nylon insert locknuts are reusable a couple of times, however the nylon's holding power degrades with each use.
