Ruwag Nyloc Nut 16mm (5) is a set of locking nuts designed to secure fasteners in automotive and mechanical assemblies where vibration resistance is critical. This part uses nylon insert technology to prevent loosening under stress and maintain tightness with repeated use.
The 16mm size indicates the thread diameter, which must be matched precisely to your vehicle or machinery’s bolt specifications. Buyers should compare this nut’s dimensions with their original to ensure compatibility, especially if replacing worn or damaged locking nuts.
This listing provides a pack of five new units, ideal for multiple fastening needs or spare stock. The “Ruwag” brand identifier suggests a particular manufacturing origin, but the core function remains the same: reliable locking to enhance joint integrity. The nyloc feature helps maintain secure assembly in engines, chassis components, suspension parts, or other areas subject to vibration.
