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

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 and prevent loosening from small amounts of vibration.

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.

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.
