Quick answer: Nylon insert nuts, split washers, jam nuts and prevailing torque nuts all rely on friction to resist loosening. Friction varies from joint to joint and drops away under vibration and dynamic loading. A wedge lock washer works differently. It uses a pair of interlocking cam faces with an angle steeper than the thread…
