PARÁMETROS DEL PRODUCTO

Wedge-Lock Security: DIN 25201 technology utilizes tension instead of friction to ensure 100 percent vibration resistance under extreme dynamic loads.
High-Tensile Compatibility: Precision hardened spring steel construction (HV 465 plus) specifically designed for Grade 8.8, 10.9, and 12.9 bolt connections.
Phosphate Black Engineering: Specialized surface coating provides stable friction coefficients and consistent torque-tension ratios for industrial assembly.
Error-Proof Pre-Assembly: Pairs are pre-assembled and glued to guarantee correct wedge cam orientation, significantly reducing installation time and risk.
Certified Anti-Vibration: Fully compliant with DIN 25201 standards and validated by Junker vibration testing (DIN 65151) to prevent spontaneous loosening.

Key Feature	Technical Specification	Operational Benefit (Trust Driver)
Wedge Cam Logic	Cam Angle (Alpha) is greater than Thread Pitch (Beta).	Prevents bolt rotation by increasing tension if loosening is attempted.
Material Strength	High-grade Spring Steel (Heat Treated).	Maintains structural integrity and bite under high clamping forces.
Surface Treatment	Phosphate Black (Phosphated).	Provides essential dry-film lubrication and basic industrial corrosion protection.
External Serrations	Precision radial grip teeth.	Ensures high-friction contact with both the bolt head and the workpiece surface.

Preguntas Frecuentess

Q1: Why is phosphate black finish important for these washers?

For high-hardness spring steel, phosphate black offers a stable friction coefficient without the risk of hydrogen embrittlement often found in electro-plating, ensuring safe use with 12.9 grade bolts.
