Professional Applications & Engineering Value
Engineered for demanding industrial applications, these M8 flat washers address critical challenges in machinery assembly, automotive manufacturing, and structural frameworks. The zinc yellow-chromate plated steel material provides a robust barrier against moisture, chemicals, and oxidation, preventing fastener failure in corrosive settings. With precise metric dimensions (8.5mm ID, 16mm OD) and controlled thickness, they evenly distribute clamping force, reduce vibration-induced loosening, and protect surfaces from galling. Ideal for fastening solutions in electrical enclosures, outdoor equipment, and heavy-duty assemblies, these washers deliver consistent performance under dynamic loads while meeting stringent DIN 125 standards for reliability and safety.
Specification Summary & Compliance
This flat washer adheres to DIN 125 dimensional and tolerance requirements, with an inner diameter of 8.5mm, outer diameter of 16mm, and thickness range of 1.4-1.5mm. Manufactured from steel with a Rockwell C15 hardness rating, it ensures mechanical integrity under stress. The zinc yellow-chromate plating offers enhanced corrosion protection, complying with RoHS and REACH environmental directives for safe usage in regulated industries.
