Stamped Galvanized Washers & Red Plastic Cover

Secure mounting interfaces and protect exposed fasteners with this assembly set, featuring galvanized steel washers and a vibrant red plastic cover. The metallic components provide a stable load-bearing surface for bolt heads or nuts, while the polymer cap offers visual identification and environmental shielding for the underlying hardware in industrial machinery or automotive applications.

The steel washers exhibit a uniform zinc plating finish, ensuring corrosion resistance and consistent thickness for reliable clamping force distribution. Manufacturing relies on precision stamping processes to maintain strict concentricity between the outer diameter and central clearance hole, preventing misalignment during assembly. The plastic cover is molded with a smooth, domed profile and a central aperture, designed to snap-fit or press-fit over the washer and fastener head for a clean, finished appearance.

Our Tianjin facility leverages high-speed pneumatic presses for efficient metal stamping and integrates professional mold development capabilities for custom plastic components. Quality control focuses on verifying coating adhesion, dimensional tolerances of the stamped apertures, and the fitment integrity of the plastic-to-metal interface. We support OEM specifications for material grades, plating standards, and color matching to meet diverse project requirements across the automotive, electronics, and general manufacturing sectors.
