Professional Applications & Engineering Value

This M20 spherical washer is engineered to solve critical alignment challenges in heavy-duty mechanical systems, such as construction machinery, automotive suspensions, and industrial equipment. Made from 18-8 stainless steel, it resists corrosion from moisture, chemicals, and extreme temperatures, ensuring reliability in demanding environments. The spherical design allows for a ±3° angular correction, which compensates for misaligned surfaces and distributes loads evenly across the joint. This reduces wear, prevents bolt fatigue, and maintains tight fastening under dynamic loads. By meeting DIN 6319 standards, it provides consistent performance in metric applications, making it ideal for replacements in male washer assemblies where precision and durability are paramount.

Specification Summary & Compliance

The washer features precise dimensions: Female ID of 23.2mm, Female OD of 36.0mm, Male ID of 21mm, Male OD of 36mm, and thickness between 11.4–11.9mm, ensuring accurate fit for M20 screw sizes. It conforms to DIN 6319 specifications for dimensional tolerances and performance. Additionally, it is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, affirming its safety and environmental standards for industrial use.
