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.

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

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

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

The extra-tall sleeve extends into holes to provide more protection than other rolled-collar washers.

With greater diameters and/or thicknesses than general purpose washers, these washers cover oversized holes or act as spacers and levelers. Clipped to fit where standard washers can’t, they won’t rotate when you position the flat edge against a flat surface.

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

Reinforce holes in soft material to keep them from collapsing around screws.

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

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

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.

These washers have smaller outside diameters than standard spring lock washers to fit neatly under socket head cap screws.

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.

These washers are rated to withstand pressure up to 100 psi.
