Hard Fiber Washers
 |
The least likely to scratch or mar delicate mounting surfaces, these washers are made of hardened cotton fiber. They are also naturally nonconductive, so they are a great choice for insulating nuts and screws to prevent unintended charges. However, fiber washers will break down faster than other washers and will need to be replaced more often.

Sealing Washers
Prevent leaks while distributing weight evenly under nuts and screws. These washers compress as you tighten to keep air and fluid in, and dust and contaminants out. Use them anywhere you need a tight seal, such as protecting electronics from moisture or keeping lubricants contained in machinery.
Hard Fiber
 |
An economical alternative to metal crush washers, these compress easily to create a seal with less effort. However, fiber washers degrade faster than metal washers and aren't as heat resistant. They also don't seal quite as tightly as their plastic or rubber counterparts. These washers are reusable, as long as the material isn't damaged.

Insulating Sleeve Washers
Cover screw threads to stop electrical current in its tracks and prevent short circuits. These washers create a barrier between the screw threads and the mating surface when mounted in through holes. This barrier also extends the life of your assembly by preventing galvanic corrosion, which is when two different metals rust more quickly due to contact with each other.
Flat Edge
 |
The flat edge distributes weight evenly to take pressure off screw heads.
Hard Fiber—The least likely to scratch or mar delicate mounting surfaces, such as printed circuit boards. These washers provide a moderate amount of electrical insulation, but they don't block current as well as plastic or ceramic washers.
