Use these metric washers to evenly distribute the load under bolt or screw heads and nuts when fastening. They can also act as spacers.

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

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.

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

The combination of internal and external teeth boosts gripping power to maintain a tight hold and provide more vibration resistance than other tooth lock washers. Use with fasteners that have heads large enough to make contact with the external teeth, such as pan, button, and binding head screws.

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.

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.

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

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.

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

Made of aluminum, these spacers are lightweight and mildly corrosion resistant.

Brass makes these spacers electrically conductive and the zinc-plated finish adds corrosion resistance.
