Professional Applications & Engineering Value

This 18-8 stainless steel wave washer delivers exceptional engineering value in demanding applications where vibration resistance and corrosion protection are critical. The wave design provides continuous spring force that compensates for thermal expansion, wear, and settling in assembled components. Made from stainless steel with Rockwell C45 hardness, it maintains its mechanical properties in high-temperature and corrosive environments common in automotive, machinery, and industrial equipment. The precise 1.56" ID and 2.38" OD dimensions ensure perfect compatibility with standard 1 1/2" screws, while the 0.016" thickness and wave profile offer optimal deflection characteristics for reliable tension maintenance in bolted connections subject to dynamic loads and thermal cycling.
