OEM Wedge Lock Washers DIN25201 Supplier - 500+ Hours Salt Spray Tested for Heavy Machinery

The DIN25201 wedge lock washers are precision-engineered fastening components designed to prevent bolt loosening under vibration and dynamic loads. These washers utilize a unique wedge-locking mechanism that increases clamping force when subjected to vibration, making them ideal for critical applications where bolt security is paramount.

Manufactured from high-grade 65Mn spring steel, our DIN25201 washers undergo strict quality control to ensure consistent hardness (HRC 45-48) and durability. The standard Dacromet surface treatment provides excellent corrosion resistance, withstanding 500+ hours in salt spray tests.

Available in a comprehensive size range from M3 to M80, these washers feature:

- Wedge angle design for positive locking action

- Reusable construction for maintenance applications

- Temperature resistance from -196°C to +800°C

- Compatible with standard wrench sizes

The washers are supplied in pairs with mating surfaces pre-glued for installation convenience. Each pair creates a self-locking system that maintains tension without requiring special tools or additional fasteners.

Applications include:

- Heavy equipment and machinery

- Structural steel connections

- Transportation infrastructure

- Energy generation systems

- Industrial processing equipment
