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.

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

Mica washers withstand temperatures up to 1050° F.

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

These washers have a flat bottom and high walls to protect metal screw heads from electrical current.

Plastic washers are good electrical insulators.

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

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

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

Plastic washers resist moisture, chemicals, and friction and are good electrical insulators.

Repair sagging, cracked plaster with these washers. The holes allow plaster to flow through to form a secure bond between the washer and the wall.

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.

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.

Slightly domed with an oversized outside diameter, these washers distribute your fastener's load over a larger surface area than other internal-tooth lock washers to limit damage to soft material.

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.

Designed for use with plastic screws, these acetal washers are good electrical insulators. They are excellent for use under water and in rotating assemblies.

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 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 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 curved, flexible washers act like springs to compensate for tolerance variations and uneven surfaces.

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

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

18-8 stainless steel spacers have good corrosion resistance.

Brass makes these spacers electrically conductive and the zinc-plated finish adds corrosion resistance.

The anodized coating on these lightweight spacers provides increased abrasion resistance over uncoated aluminum.

Almost nonabsorbent, these unthreaded LDPE and HDPE spacers won't swell when exposed to water.

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

Use PEEK spacers as an alternative to metal spacers in high-temperature, high-stress applications. They resist chemicals, wear, and moisture.

Protect components from electrical charges.

A zinc-plated finish gives these steel inserts mild corrosion resistance.
