Single-Wave Washers
These curved, flexible washers act like springs to compensate for tolerance variations and uneven surfaces. You can also use them to damp vibration.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.
316 stainless steel washers have excellent resistance to chemicals and salt water. They may be mildly magnetic.
