ASME B18.16.6 (NE):2017 NE Type Nylon Insert Lock Nut is designed for anti-loosening connections in inch-thread systems. The nylon insert creates additional resistance during installation, helping maintain thread stability under vibration.
It is commonly used in automotive repair, machinery, appliance hardware, outdoor facilities, and general industrial applications. The NE type supports procurement and replacement under ASME standards and can be matched with inch bolts and studs.
Different materials, grades, and surface treatments can be supplied to meet requirements for rust protection, installation feel, and consistency in batch assembly.
