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.

Designed for use with A325 structural screws, studs, and nuts, these washers are often used for construction and exterior building applications.

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

These washers can withstand temperatures up to 450° or 500° F without degrading.

Also known as shoulder washers.

As you tighten your screw, the rolled collar compresses under the head to create an insulating barrier between a screw shank and a mating surface.

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.

A specially shaped ID grips your screw shank tightly.

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

Use on clamps with open arms to keep the holding screw in place.

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.

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

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

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.

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.

Create a stronger seal than metal or rubber alone. These one-piece washers are metal for strength with a bonded rubber seal that creates a tight grip.

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

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

These leather washers are nonmarring.

These polyurethane washers withstand wet conditions as well as sunlight, ozone, and some chemicals.

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

18-8 stainless steel spacers have good corrosion resistance.

These spacers have excellent corrosion resistance and are passivated for enhanced protection.

These spacers have excellent wear and abrasion resistance. Exposure to moisture may cause them to expand.

Naturally slippery and wear resistant, acetal spacers also offer some resistance to moisture.

Protect components from electrical charges.

A nickel-chrome plating gives these spacers a mirror-like finish.
