Compared to our general purpose washers, these have exaggerated diameters and/or thicknesses for covering oversized holes or for use as spacers and levelers.

SAE washers generally have a smaller ID and OD than USS washers.

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 washers can withstand temperatures up to 500° F without degrading.

Square washers fit into slots and channels and have flat sides to keep them from rotating.

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

A slot in the side allows you to install and remove these washers without completely disassembling your joint.

Also called No. 10 Western Timber and Victor washers, these have large ODs to prevent screws from sinking into wood. The notches allow you to temporarily secure them with nails to keep them from rotating during installation.

Choose these washers for their adherence to strict military standards for material and construction.

Compared to standard split lock washers, these are thicker and have larger outside diameters.

Internal teeth dig into the screw head while the smooth outside edge won't snag objects. Use with fasteners that have small heads, such as fillister and cheese head screws.

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.

Bend one tab against the side of the mounting surface and the other tab against the flats on a bolt or nut to prevent both the fastener and washer from turning and loosening in high-vibration applications, such as a motor mount.

Also known as thread-sealing washers, use these under nuts and other washers.

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

These washers surpass other rubber washers when it comes to withstanding oil, grease, and fuel.

These leather washers are nonmarring.

These wool felt washers can be soaked with oil to lubricate joints.

Spin these shims onto screw threads to extend the shoulder length.
