Product Description
DIN9250 Serrated Safety Washer: Combine Friction and Mechanical Lock for Maximum Security
Maximum fastener security demands an engineered synergy of friction and mechanical locking—a principle masterfully realized in the DIN9250 Serrated Safety Washer. Unlike conventional washers that rely solely on clamping force, this innovative component integrates dual-security mechanisms for unparalleled performance.
Dual-Security Mechanism
The washer's precision-machined gear surface generates intense frictional resistance while the serrated tooth profile creates mechanical interlock, forming an unbreakable barrier against vibrational loosening. The gear teeth, typically engineered with 45°-60° angles, bite into both the fastener head and mating surface during installation, transforming static friction into dynamic resistance that prevents micro-rotations even under cyclic loading.
Validated Performance
This unique design has been validated through rigorous ISO 16130 vibration testing, where the DIN9250 maintained 90% of initial preload after 10,000 cycles—outperforming standard washers by over 300% in anti-loosening performance.
Technical Specifications
- Size range: M1.6 (precision electronics) to M36 (heavy machinery)
- Material options: High-carbon steel for strength, 304/316 stainless steel for corrosion resistance
- Custom solutions available for non-standard diameters, tooth profiles, or exotic materials like titanium
- Fully compliant with DIN 9250 standards and ISO 9001 quality certification
Application Versatility
Engineered for industrial versatility, the DIN9250 ensures long-term fastener integrity in critical applications including automotive powertrains, industrial robotics, and construction equipment.
