Bend one tab against the side of the mounting surface and the other tab against the flats on a bolt or nut to prevent both the fastener and washer from turning and loosening in high-vibration applications, such as a motor mount.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.
Zinc-plated steel washers are corrosion resistant in wet environments.
