Professional Applications & Engineering Value

These M5 flat washers deliver exceptional engineering value through their zinc yellow-chromate plated steel construction, specifically designed to address common industrial challenges. The advanced surface treatment provides superior corrosion resistance, making them ideal for applications exposed to moisture, chemicals, or outdoor conditions where fastener integrity is critical. The precise metric dimensions and compliance with DIN 125 and ISO 7089 standards ensure consistent performance in automotive assemblies, machinery manufacturing, and electrical enclosures. The controlled thickness variation (0.9-1.1mm) maintains optimal pressure distribution, preventing joint loosening and surface indentation while accommodating manufacturing tolerances. This combination of material properties and dimensional accuracy solves vibration-related failures and extends maintenance intervals in demanding industrial applications.

Specification Summary & Compliance

This flat washer features precise metric dimensions with 5.3mm inner diameter, 10mm outer diameter, and thickness ranging 0.9-1.1mm, manufactured to exacting Class 2A tolerance standards. The product strictly conforms to DIN 125 and ISO 7089 specifications for dimensional accuracy and performance requirements. Compliance certifications include RoHS 3 (2015/863/EU) for hazardous substance restriction and REACH (EC 1907/2006) for chemical safety, ensuring environmental responsibility and regulatory adherence for global industrial applications.
