Professional Applications & Engineering Value
This M2 flat washer is engineered to address common industrial challenges such as fastener loosening, material degradation, and assembly failure. Crafted from passivated 18-8 stainless steel, it provides robust protection against corrosion, making it suitable for applications in electronics, automotive, and machinery where exposure to moisture and chemicals is a concern. The precise metric dimensions (2.2mm ID, 7mm OD) and controlled thickness ensure even pressure distribution, reducing the risk of joint fatigue and improving the integrity of M2 screw connections. With its Rockwell B75 hardness, this washer maintains shape under load, offering long-term reliability in high-vibration environments and supporting efficient, low-maintenance operations for B2B clients.
Specification Summary & Compliance
This flat washer features a 2.2 mm inner diameter, 7 mm outer diameter, and thickness ranging from 0.6 to 1.0 mm, designed for M2 screw sizes in metric systems. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards. The material, 18-8 stainless steel with passivation, and hardness of Rockwell B75 confirm consistent quality and durability for industrial use.
