Professional Applications & Engineering Value

These M14 metric flat washers deliver critical performance in electrical and mechanical systems where reliable conductivity and environmental sealing are paramount. The cellulose-filled copper construction addresses common industrial challenges by providing stable electrical paths for grounding applications while resisting galvanic corrosion in mixed-metal assemblies. Engineers specify these DIN 7603 compliant washers for transformer connections, switchgear installations, and automotive electrical systems where consistent thickness (1.8-2.2mm) ensures proper compression sealing against fluids and gases. The material's inherent malleability accommodates surface irregularities, creating superior seals in high-vibration environments while maintaining electrical continuity throughout the service life.

Specification Summary & Compliance

Manufactured to DIN 7603 dimensional standards with inner diameter 14.2mm, outer diameter 17.9mm, and thickness tolerance 1.8-2.2mm. These metric flat washers comply with RoHS 3 (2015/863/EU) environmental directives and are engineered for M14 screw applications requiring precise fitment and reliable performance in electrical and sealing assemblies.
