Brighton-Best Nylon Locknuts - Locknuts are nuts that resists loosening under vibrations and torque. Fasteners are typically made of low-carbon steel. Coarse threads are better when working with brittle materials; they are sturdier and are easier to thread and unthread compared to fine. Coarse threading also allows for thicker coatings and platings. Porteous (PFC) 00250-2400-401.
