Polyamide PA66 (Nylon) Lock Nut

Polyamide PA66 (Nylon) Lock Nut, available in metric sizes M3 and M4, is known for its outstanding mechanical strength, heat resistance, and moisture resistance. PA66 stands apart from other polyamide grades due to its higher melting point and enhanced rigidity, making it particularly suited for high-stress, high-temperature environments. It retains its shape and strength even in challenging conditions, such as in automotive and aerospace applications. While other grades like PA6 also offer excellent performance, PA66 excels where additional toughness and thermal stability are required, such as in environments exposed to heat, oils, greases, and vibration. PA66’s lower moisture absorption compared to other nylon grades further ensures long-term dimensional stability, even in humid conditions.
