Products Detail

DIN 980 is a widely recognized German standard for all-metal prevailing torque self-locking hex nuts, specially designed to solve loosening problems caused by vibration, impact and alternating dynamic loads. Different from ordinary standard hex nuts, DIN 980 nuts adopt a professional all-metal deformation self-locking structure, featuring reliable anti-loosening performance without the need for additional gaskets, nylon rings or auxiliary locking accessories. It can achieve repeated locking and maintain stable fastening preload for a long time, becoming an essential high-reliability fastener for mechanical and structural dynamic working conditions.
Our factory provides professional DIN 980 self-locking hex nuts with mainstream strength classes of8 and 10, adapting to medium and heavy-load industrial fastening requirements. The products are forged from high-quality carbon steel and alloy steel materials, with a complete production size range coveringM12–M36. Adopting integral forging and precision tapping technology, all nuts feature smooth thread surface, accurate thread tolerance and excellent meshing performance, ensuring precise assembly and good interchangeability with standard metric bolts.
All DIN 980 self-locking nuts are manufactured and processed in strict accordance with DIN standard specifications. Corresponding strength grades are treated with standardized heat treatment as required, ensuring stable hardness, excellent tensile strength and lasting prevailing torque performance. The unique structural design enables the nuts to generate continuous elastic clamping force on the thread pair, effectively resisting loosening caused by mechanical vibration, equipment operation and environmental impact. These self-locking nuts are widely used in mechanical manufacturing, vehicle equipment, steel structure facilities, power engineering and industrial automation equipment, providing safe, stable and maintenance-free fastening solutions for dynamic working scenarios.
