This NM/NE-type self-locking hex nut is manufactured to ASME B18.16.6 standards and features a nylon insert that serves as the locking mechanism. This built-in feature helps prevent the nut from loosening due to vibration or mechanical stress. The nut is made from plain steel, meaning it has no coating or surface treatment and offers little inherent resistance to corrosion. It has a strength grade of Gr.N8 and Unified National Coarse (UNC) threading.
