Coupling Nuts
Locking strength for high-vibration and critical load applications

Our Castellated Nuts in Chennai are engineered for safety-critical applications that require secure locking in high-vibration environments. Featuring precisely cut slots on their crown, these nuts are designed to be used with a cotter pin and a drilled bolt, preventing rotation and loosening under dynamic load. Ideal for automotive, aerospace, and machinery applications, they offer enhanced locking performance over standard nuts. Manufactured using high-quality materials and industry-certified finishes, these nuts are built to withstand the toughest operating conditions while ensuring safety and stability.
