Professional Applications & Engineering Value

This M8 zinc-plated steel flat washer is engineered to address common industrial challenges such as corrosion-induced failure and uneven load distribution. The zinc plating provides a protective barrier against moisture and chemicals, significantly enhancing corrosion resistance in outdoor or high-humidity settings like automotive underbodies and marine equipment. Its adherence to DIN 6340 ensures precise dimensional tolerances, preventing misalignment and reducing stress concentrations in metric fastening systems. By distributing loads evenly across surfaces, this washer minimizes wear on connected components, making it ideal for industrial applications in machinery assembly, structural frameworks, and electronic enclosures where reliability and longevity are critical.

Specification Summary & Compliance

This flat washer features an inner diameter of 8.4mm, outer diameter of 23mm, and thickness range of 3.7-4.3mm, designed for M8 screw sizes with standard metric dimensions.
