Compared to our general purpose washers, these have exaggerated diameters and/or thicknesses. Use them to cover oversized holes, hold heavy fastening loads, or as spacers and levelers.

When you’ve applied the correct tension, these washers release an orange dye as a visual indicator.

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.

Flat and oval head screws sit flush within these metric washers for a neat, finished appearance.

A specially shaped ID grips your screw shank tightly.

Also known as shoulder washers.

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

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

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

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

The teeth on these washers bite further into the screw head and joint than standard external-tooth washers to provide a stronger 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 crush washers, these compress when tightened to form a tighter, more durable seal than rubber washers. They are commonly used to seal fluids such as oil and fuel.

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

Slide these shims under the screw head to shorten the shoulder length.

As a screw is tightened, these washers flatten to add tension to the joint and prevent loosening from small amounts of vibration.
