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 come with a traceable lot number and a physical and chemical test report.

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

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.

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.

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

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

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

Cover oversized holes and the ends of tubes and pipe with these cup-shaped washers.

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.

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.

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.

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

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.

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.

Polypropylene spacers have a hard surface and resist many chemicals and solvents.

Protect components from electrical charges.

With their mirror-like finish, these are the go-to spacers when appearance matters.

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