About Washers

Belleville Spring Lock Washers
Also known as conical washers, these have a slightly cupped shape that gives them spring-like flexibility to grip tighter than split and tooth lock washers. They minimize loosening from wear, temperature changes, and vibration. Load-rated Belleville disc springs are also available.
18-8 stainless steel and 17-7 PH stainless steel washers have good chemical resistance and may be mildly magnetic. 17-7 PH stainless steel washers are stronger than 18-8 stainless steel washers.

Metric Split Lock Washers
As you tighten a bolt, these metric washers flatten to add tension to the threaded joint and prevent loosening from small amounts of vibration. They meet a DIN or ASME standard for split lock washer dimensions.
Curved and wave split lock washers can be used with fasteners that have right- or left-hand threads to prevent clockwise and counterclockwise rotation. These washers are reusable—they retain their shape when untightened and will not damage fasteners. Steel washers are stronger and resist wear better than zinc-plated steel and stainless steel washers. Use them in dry environments.

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.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.
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.
