All-Metal Prevailing Torque Nut

A lock nut with a crimped top that grips the bolt thread, so it stays tight under vibration. The crimped section deforms elastically to create friction on the thread, preventing loosening without a separate insert. Install with a standard wrench; no special tool is needed. Typical uses include engines, vehicles, and machinery where joints run hot or vibrate.
