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.

When you’ve applied the correct tension, these washers release an orange dye as a visual indicator.

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

A specially shaped ID grips your screw shank tightly.

As you tighten a bolt, these metric washers flatten to add tension to the threaded joint and prevent loosening from small amounts of vibration.

The arched shape of these washers presses up against a bolt and down against a nut to prevent loosening from wear, vibration, or temperature changes.

Designed for use with plastic screws, these acetal washers are good electrical insulators. They are excellent for use under water and in rotating assemblies.

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

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.

Bend the tab of these metric lock washers against the flats of a hex nut or bolt head to prevent the fastener and washer from turning and loosening due to vibration, wear, or changes in temperature.

Able to withstand pressure greater than 7,000 psi, these one-piece bonded washers create the tightest seals.

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

Slide these shims under the screw head to shorten the shoulder length.

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