KYOUJIN Metric Flat Washers conforming to ISO 7089 are high-performance fastening components engineered for applications requiring exceptional mechanical strength, dimensional stability, and lightweight construction. Manufactured from advanced carbon fiber reinforced thermoplastic composite material, KYOUJIN washers provide outstanding load-bearing capability while offering significant weight savings compared to metal alternatives.
Designed for use with metric fasteners, KYOUJIN flat washers distribute clamping forces evenly, protect mating surfaces, and improve joint reliability in demanding assemblies. Their high stiffness, excellent fatigue resistance, and corrosion-free construction make them ideal for aerospace, motorsport, robotics, semiconductor, and advanced engineering applications.
