Professional Applications & Engineering Value

This brass SAE flat washer is engineered to address common industrial challenges such as galvanic corrosion, vibration-induced failure, and electrical isolation. The brass material inherently resists oxidation and chemical degradation, making it suitable for plumbing, marine, and electrical grounding applications where moisture or aggressive media are present. With a 1.625" ID tailored for 1 1/2" screw size, it ensures a snug fit that prevents misalignment and distributes clamping force evenly across the 3" OD surface. This reduces stress concentration on connected components, enhancing joint integrity in heavy-duty machinery, HVAC systems, and construction projects. The combination of corrosion resistance and precise SAE inch dimensions delivers reliable performance in demanding settings, minimizing downtime and maintenance costs.

Specification Summary & Compliance

This washer adheres to SAE standards with an inner diameter of 1.625", outer diameter of 3", and thickness ranging from 0.153" to 0.213", ensuring dimensional accuracy for Class 2A fit applications. It is manufactured from brass and is fully compliant with REACH (EC 1907/2006) regulations as of June 14, 2023, confirming it is free from 235 SVHCs. This makes it suitable for global industrial use where environmental and safety standards are critical.
