The K Lock Nut is a precision-engineered, all-metal prevailing torque lock nut designed to provide exceptional resistance to vibration and loosening. Conforming to the DIN 980M standard (M-Type), this hexagonal nut utilizes a reusable one-piece construction that ensures reliable performance in critical applications. The fundamental principle of the K Lock Nut involves an engineered distortion in its structure, which creates a consistent frictional force on the mating bolt threads. This design offers a significant advantage over standard nuts by maintaining clamp force under dynamic loads, making it an essential component for safety-critical assemblies.
Manufactured from high-grade stainless steel, the K Lock Nut offers superior corrosion resistance and durability. The all-metal construction eliminates the limitations associated with non-metallic insert lock nuts, ensuring performance integrity in harsh environments exposed to chemicals, moisture, and extreme temperatures. This material selection provides long-term reliability and prevents the degradation common in nylon-insert fasteners, making it suitable for applications requiring prolonged service life without maintenance.
A distinguishing feature of the K Lock Nut is its exceptional performance in high-temperature environments. Unlike DIN 985 (nylon insert) and DIN 982 (all-metal) lock nuts, this nut is specifically engineered to maintain its locking capabilities at temperatures exceeding 150°C. This thermal stability makes it particularly valuable for applications in automotive systems, industrial machinery, and energy sector equipment where elevated temperatures would compromise alternative locking solutions.
The design of the K Lock Nut focuses on both reliability and practicality. The M-Type configuration provides consistent prevailing torque characteristics through multiple reuse cycles, offering cost-effectiveness through extended service life. The nut’s construction ensures uniform locking force distribution, preventing thread damage while maintaining secure fastening integrity. These characteristics make it suitable for applications where vibration resistance and maintenance-free operation are paramount requirements.
The K Lock Nut represents an advanced fastening solution for demanding industrial applications. Its combination of all-metal construction, high-temperature capability, and reusable design positions it as a superior choice for engineers seeking reliable vibration-resistant fastening. The K Lock Nut meets rigorous international standards while providing practical advantages in manufacturing, maintenance, and long-term performance across various industrial sectors.
