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.

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

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

The extra-tall sleeve extends into holes to provide more protection than other rolled-collar washers.

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.

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.

The teeth on these washers bite further into the screw head and joint than standard external-tooth washers to provide a stronger hold.

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.

Comparable to NORD-LOCK® and Sherex TEC Series 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.

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

These washers surpass other rubber washers when it comes to withstanding oil, grease, and fuel.

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 curved, flexible washers act like springs to compensate for tolerance variations and uneven surfaces.

Spin these shims onto screw threads to extend the shoulder length.

18-8 stainless steel spacers have good 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.
