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.

Compared to our general purpose washers, these have exaggerated diameters and/or thicknesses for covering oversized holes or for use as spacers and levelers.

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

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 are excellent electrical insulators.

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

Mica washers withstand temperatures up to 1050° F.

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.

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

As a screw is tightened, these washers flatten to add tension to the joint, counteracting fatigue around the joint from small amounts of vibration.

Also known as high-collar lock washers, these have a smaller outside diameter than standard split lock washers to fit neatly under socket head cap screws.

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

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

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.

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