Professional Applications & Engineering Value
These SAE flat washers in 18-8 stainless steel address common industrial challenges such as fastener loosening, surface damage, and corrosion-induced failures. The flat washer design evenly distributes clamping force, preventing stress concentration on soft materials and maintaining joint integrity under vibration. With excellent corrosion resistance, they are suited for outdoor equipment, marine applications, and chemical processing plants where moisture and corrosive agents are present. The precise 0.125" ID and 0.312" OD dimensions ensure a snug fit on No. 4 screw fasteners, reducing installation errors and enhancing assembly efficiency in automated or manual production lines.
Specification Summary & Compliance
This washer meets ASME B18.21.1 dimensional and manufacturing standards for consistent performance. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring no restricted hazardous substances are used. The material, 18-8 stainless steel, provides inherent strength and durability without additional hardness ratings, making it suitable for general-purpose industrial use where corrosion resistance and reliability are prioritized.
