Professional Applications & Engineering Value
This black corrosion-resistant steel flat washer addresses critical challenges in industrial maintenance and assembly operations. The specialized corrosion-resistant coating provides essential protection against rust and degradation in manufacturing facilities, outdoor equipment, and marine-adjacent applications where moisture exposure compromises fastener integrity. Engineered with precise 3/8" screw sizing and optimal dimensional ratios, it prevents joint loosening under vibration while distributing clamp load effectively across softer materials. The Grade 2 classification ensures reliable performance in general-purpose applications from machinery assembly to structural steel connections, offering a cost-effective solution that balances durability with regulatory compliance for global supply chains.
Specification Summary & Compliance
Manufactured to inch system standards with critical dimensions of 0.406" ID x 1.5" OD and thickness range of 0.051-0.084". Features Grade 2 strength classification for general industrial use. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, including the latest SVHC updates as of June 2023, ensuring environmental safety and unrestricted international distribution.
