顺吉楔形防松螺纹

2023-9-6

  • Thread loosening is the "invisible killer" of mechanical equipment. However, the 30° wedge nut thread, with its revolutionary structural design, fundamentally solves the loosening problem, making it the first-choice fastening solution for scenarios with high vibration and high safety requirements, ensuring every connection is as firm as a rock.

    Core Advantage 1: Tighter Under Vibration, Anti-loosening Performance Crushes Traditional Threads

    • The unique 30° wedge-shaped inclined surface structure converts axial loosening force into radial locking force. Its normal pressure is twice that of ordinary threads, and the anti-loosening friction is increased by more than 3 times.
    • Verified by Junkers vibration test: After 2 minutes of lateral vibration, ordinary nuts loosen completely, torque-locking nuts lose 70% of their locking force, while the 30° wedge nut still maintains complete self-locking capability.
    • Under extreme environments such as 8-degree seismic intensity and level 12 gusts, the preload attenuation rate is only 1/5 of that of ordinary threads. It has passed stringent certifications such as DIN 65151 and GJB715.3A.
