Professional Applications & Engineering Value

This brass flat washer delivers exceptional engineering value in demanding applications where corrosion resistance and electrical conductivity are critical. The copper alloy construction prevents galvanic corrosion when paired with dissimilar metals, making it ideal for marine, plumbing, and electrical systems. With its 0.781" ID precision-matched to 3/4" screw size, it eliminates loose fittings that cause vibration-induced failures in machinery and structural assemblies. The 1.625" OD provides superior bearing surface distribution, protecting soft materials from embedding and maintaining clamp load integrity in heavy-duty industrial equipment, automotive systems, and commercial construction projects.
