Use these metric washers to evenly distribute the load under bolt or screw heads and nuts when fastening. They can also act as spacers.

Also known as Type B washers, these distribute your fastener's load over a larger surface area than other washers to minimize damage to soft materials.

These metric washers surpass most other plastic washers when it comes to withstanding chemicals, oil, and grease.

Low moisture absorption and good heat resistance make these metric washers suitable for wet and harsh environments.

These metric washers hold up in blistering temperatures up to 3000° F.

Plastic washers are good electrical insulators.

Also known as shoulder washers.

Clipped to fit where standard washers can't, these won't rotate when you position the flat edge against a flat surface.

As you tighten a bolt, these metric washers flatten to add tension to the threaded joint and prevent loosening from small amounts of vibration.

Teeth on the outside edge of these metric washers bite into the screw head and joint for a tight grip.

To keep 90° countersunk screws from loosening in vibration applications, the teeth on these washers bite further into the screw head and joint than standard external-tooth lock washers for a more secure hold.

The combination of internal and external teeth boosts gripping power to maintain a tight hold and provide more vibration resistance than other tooth lock washers. Use with fasteners that have heads large enough to make contact with the external teeth, such as pan, button, and binding head screws.

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.

Sunlight, ozone, and water won’t affect these washers.

These washers withstand harsh chemicals such as acetic acid and isopropyl alcohol.

With three points of surface contact, these washers provide more stability than single-wave washers.
