Nylon insert lock nuts, also called Nylock nuts, are hex nuts with a built-in nylon ring that creates resistance to loosening and vibration. When the threaded fastener reaches the collar, the nylon insert forms a tight, compressive hold that keeps assemblies secure.
These are standard DIN 985 lock nuts and are available in zinc or black oxide coated steel, A2 stainless steel, and A4 (316) marine grade stainless steel for superior corrosion resistance.
