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

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

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

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.

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.

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

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.

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

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

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

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

The teeth on these washers firmly grip heads of 82° flat head countersunk screws.

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

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.

Also known as NORD-LOCK® washers, these two-piece washers provide more locking power than split, tooth, and spring lock washers. Wedges on the inside lock the two pieces together, and serrations on the exterior grip surfaces to resist loosening from high vibration and shifting.

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

Made of durable material, these washers resist wear from rubbing and scraping surfaces.

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 are rated to withstand pressure up to 100 psi.

With three points of surface contact, these washers provide more stability than single-wave washers.

These SBR rubber washers are reinforced with cloth fibers.

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

Made of aluminum, these spacers are lightweight and mildly corrosion resistant.

The zinc plating provides some corrosion resistance.

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

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

PTFE spacers have a slippery surface and surpass most plastic spacers when it comes to chemical resistance and performance in extreme temperatures.

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

Made of FDA-listed material, these clear spacers can be used in food and beverage applications.

With flexible teeth that slide smoothly over threads of any pitch, these push nuts can be used alone for light-duty applications or as a jam nut.

Made from brass, these inserts are nonmagnetic, mildly corrosion resistant, and electrically conductive.

Easier to install than grommets, push these bushings through your mounting hole to dampen vibration. Use them with a vibration-damping washer to isolate vibration.

In addition to having a wider temperature range than our other vibration-damping grommets, these have excellent weather resistance.

In addition to having a wider temperature range than our other ribbed vibration-damping grommets, these have excellent weather resistance.
