Metal Nuts
Lock nuts, or prevailing torque nuts, are highly specialized fasteners designed to resist vibrational loosening, thermal cycling, and dynamic shock loads without relying on external locking washers. They utilize various mechanical retention mechanisms, such as deformable nylon inserts for temperatures up to 250°F, or all-metal distorted threads and serrated flanges for high-heat and extreme-stress environments. These components are essential in automotive suspension systems, aerospace airframes, and heavy industrial rotating machinery where joint failure from vibration is a critical safety concern.
