Ruwag Nyloc Nut 12mm (5) is a pack of five nylon-insert lock nuts designed to secure fastening assemblies by resisting loosening from vibration or torque. This type of auto part is commonly used where reliable, vibration-resistant fastening is critical, such as in automotive engines, suspension, and other mechanical components.
The 12mm size refers to the threading diameter, which is a key specification to compare when matching this nut to the original hardware in your vehicle or machinery. The nylon insert inside the nut provides a locking action by creating friction on the bolt thread, helping to maintain tightness under stress.
This pack contains five new Ruwag nyloc nuts, suitable for users needing a small quantity of this particular locking nut size. When replacing nuts, ensure the thread pitch, diameter, and type align with the old parts for proper fitment and safety.
