Professional Applications & Engineering Value

This M8 zinc plated steel flat washer delivers critical engineering solutions where vibration resistance and corrosion prevention are paramount. Manufactured to DIN 433 specifications, it ensures uniform pressure distribution across M8 fastener assemblies, effectively mitigating stress concentration in automotive chassis, electrical enclosures, and structural steel connections. The zinc plating provides a sacrificial layer that combats oxidation in outdoor or chemically aggressive settings, while the Rockwell C38 hardness prevents deformation under cyclic loading. Engineers specify these metric flat washers for OEM manufacturing and MRO operations to achieve long-term joint integrity without galvanic corrosion risks, supported by full compliance with international environmental directives.

Specification Summary & Compliance

This flat washer conforms to DIN 433 dimensional standards with an inner diameter of 8.4mm, outer diameter of 15mm, and thickness range of 1.4-1.8mm, engineered for precise M8 screw compatibility. Material certification includes zinc plated steel with hardness maintained at Rockwell C38. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring adherence to hazardous substance restrictions and chemical safety protocols for industrial distribution.
