Cup Shaped Washer, Concave Zinc Plated Washer

Product Introduction

Cup‑shaped washer (concave washer) is integrally stamped from high‑quality carbon steel with zinc‑plated surface for anti‑corrosion performance. The unique concave bowl structure evenly distributes bolt tightening pressure to absorb vibration and prevent surface damage of plates, also used for hole‑covering decoration. Burr‑free edge and tight dimensional tolerance ensure perfect fitting during assembly.

Product Advantages

1. Structural design: Curved bowl shape provides larger stress area, better cushioning performance than ordinary flat washers.

2. Corrosion resistance: Zinc‑plated surface resists rust even in humid or outdoor working environments.

3. Stable precision: Produced by stamping dies, consistent dimension and good interchangeability for each batch.

4. Flexible customization: Custom outer diameter, inner hole, thickness and depth according to drawings or samples.

Application Fields

Widely used in sheet‑metal chassis, engineering machinery, furniture hardware, electromechanical equipment, rail transit and other fastening assemblies for load bearing and shock absorption.
