Lock Nut

Lock Nuts are essential self-locking fasteners engineered to prevent loosening in assemblies subject to severe vibration, dynamic loading, and thermal shock. Unlike standard nuts that rely solely on clamping force, these nuts employ a prevailing torque mechanism—either via a Nylon Insert (Nylock) or an All-Metal Distorted Thread design—to create permanent friction against the mating bolt. While nylon inserts are limited by temperature, our All-Metal Inconel Lock Nuts withstand extreme heat up to 1000°C without losing their locking capability. Manufactured to standards like DIN 980, DIN 985, and IFI 100/107, our lock nuts are forged from high-fatigue alloys like Inconel 718, Inconel 625, and . This makes them indispensable for securing turbine blades, vibrating pumps, and aerospace engine components where fastener failure is not an option.
