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.

Protect components from electrical charges.

Designed for multi-level printed circuit board applications, these self-aligning, through-hole supports have a chamfered female end for stacking. The other end snaps and locks in place for a permanent connection.

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 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.

A specially shaped ID grips your screw shank tightly.

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.

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.

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

Compared to standard split lock washers, these are thicker and have larger outside diameters.

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.

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

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

These washers withstand harsh chemicals such as acetic acid and isopropyl alcohol.

Able to withstand pressure greater than 3,000 psi, these one-piece bonded washers create the tightest seals.

Also known as thread-sealing washers, use these under nuts and other washers.

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

These polyurethane washers withstand wet conditions as well as sunlight, ozone, and some chemicals.

These aluminum inserts are lightweight, nonmagnetic, and mildly corrosion resistant.
