LONGZE QUALITY SAFEGUARD & RISK MITIGATION
Profile designed exclusively to fit inside the counterbored holes of socket head cap screws (DIN 912).
Technical Risk Alert: DIN 7980 Compliance
The "Assembly Failure" Risk:
DIN 7980 components are engineered for precision retention. If the internal dimensions exceed the tolerance of your specific thread preparation before final loading, the components will detach or fail. This is the #1 cause of failure in high-speed automated production lines.
Longze Mitigation Strategy:
- Precision tolerance control within +0.1/-0mm.
- Burr-free manufacturing to prevent thread interference.
- Hardness matching (e.g., 200HV vs 300HV+) to prevent component deformation during high-torque processing.
TRANSPARENCY & GLOBAL TRADE GUARANTEE
Global supply chains require trust built on clear accountability. The LZ-Shield protocol defines our commitment to DIN 7980 quality and the boundaries of international logistics.
