Product Information

The national lock nut (K-Type Guk Lock Nut) is specifically engineered for demanding operational environments, meeting high-torque application requirements. By adjusting the axial screw torque, the national lock nut precisely optimises nut deflection accuracy, effectively resisting loosening risks under harsh conditions such as vibration and impact to ensure connection stability. Even in high-frequency stress scenarios like heavy machinery and outdoor industrial equipment, the national lock nut maintains reliable locking performance, making it suitable for applications requiring high-torque fastening and frequent operational switching. The national lock nut is made of high-strength carbon steel, processed by precision turning, thread machining and surface anti-rust treatment, which further enhances its durability and adaptability in harsh working conditions.
