The selection of raw material is critical, as it determines the washer’s strength, corrosion resistance, and overall durability in the harsh UAE climate.

Manufacturing Process

The manufacturing process begins with precision blanking of steel sheets to create the basic washer shape. This is followed by stamping operations that form the distinctive radial teeth pattern on both sides of each washer. The teeth are engineered at specific angles—typically between 25-30 degrees—to create the optimal cam effect.

Heat treatment follows, where the washers undergo hardening and tempering processes to achieve the required hardness (typically 45-50 HRC for steel washers). This ensures the teeth maintain their shape and effectiveness under extreme pressure. Surface treatments such as zinc plating, galvanizing, or specialized coatings are then applied to enhance corrosion resistance, a critical consideration for UAE’s coastal and desert environments.

The final stage involves precision grinding to ensure uniform thickness and parallel surfaces, followed by rigorous quality control inspections. Each pair of washers is carefully matched to ensure perfect interaction between the cam angles and teeth patterns.

Key Properties Derived from Manufacturing
