Professional Applications & Engineering Value

This M20 zinc-plated steel flat washer is engineered to address common industrial challenges such as fastener corrosion, uneven load distribution, and assembly instability. The zinc-plated steel material provides a durable barrier against moisture and chemicals, making it ideal for outdoor machinery, automotive systems, and construction equipment where corrosion resistance is critical. Its metric dimensions (22mm ID x 65mm OD) and compliance with ASME B18.22M standards ensure precise alignment with M20 screws, preventing thread damage and vibration-induced failures. By evenly spreading clamp load, this flat washer minimizes stress concentrations on surfaces, reducing the risk of cracking and deformation in high-stress applications like structural bolting and heavy machinery assembly.
