A self-locking nut M16x1.5 is designed to resist loosening. It features a metric thread with a 16 mm diameter and a 1.5 mm pitch. The self-locking capability is usually achieved with a nylon insert or by deformation of the nut itself, ensuring a tight grip. This type of nut is widely used in applications where vibrations occur, and stable fastening is crucial, such as in constructions, machinery, and vehicles. Due to its characteristics, the nut provides reliable security in dynamic environments.
