Professional Applications & Engineering Value

This M3 zinc plated steel flat washer delivers critical engineering solutions through its optimized material properties and standardized dimensions. The zinc plating creates a protective barrier that significantly reduces corrosion in humid or chemically aggressive environments, addressing common failure points in industrial equipment. Manufactured to DIN 125 and ISO 7089 standards, these washers ensure perfect compatibility with metric fastening systems while maintaining consistent thickness for uniform clamping force distribution. The Rockwell C38 hardness provides exceptional resistance to embedding and deformation, making these washers ideal for applications requiring repeated assembly/disassembly cycles. From machinery manufacturing to electrical enclosures, these components prevent loosening from vibration and protect sensitive surfaces from damage.

Specification Summary & Compliance

This flat washer features precise metric dimensions with 3.2mm inner diameter, 7mm outer diameter, and 0.5-0.6mm thickness manufactured to DIN 125 and ISO 7089 standards. The component maintains Rockwell C38 hardness for consistent mechanical performance and carries full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe usage across various industrial applications.
