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

Also called No. 10 Western Timber and Victor washers, these have large ODs to prevent screws from sinking into wood. The notches allow you to temporarily secure them with nails to keep them from rotating during installation.

Teeth on the outside edge of these metric washers bite into the screw head and joint for a tight grip.

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

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.

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.

Precisely shaped to fit snugly on keyed shafts, these shims align, level, and space components. Because of their tight fit, they also help components rotate in unison with the shaft.

These shims are shaped to fit over D-profile shafts. Use them to precisely align, level, and adjust spacing.
