About Washers

Triple-Wave Washers
With three points of surface contact, these washers provide more stability than single-wave washers. They are curved and flexible to act like springs, compensating for tolerance variations and uneven surfaces. You can also use them to damp vibration.

Metric 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.
Steel washers are harder and hold their shape better than stainless steel washers, but aren’t as corrosion resistant. They have a black finish from heat treatment.
