Professional Applications & Engineering Value

This M2.9 metric flat washer is precision-engineered from 18-8 stainless steel, offering excellent resistance to rust and oxidation in demanding settings such as electronics assembly, automotive components, and machinery. The flat washer design evenly distributes clamping force, preventing surface damage and maintaining joint integrity under vibration or load variations. With a 3.1mm inner diameter and 6mm outer diameter, it ensures a snug fit for M2.9 screws, reducing the risk of misalignment in compact or high-precision systems. Its corrosion-resistant properties make it suitable for outdoor, marine, or chemical-exposed applications, while the thin profile (0.2–0.4 mm thickness) supports space-constrained designs without sacrificing performance.
