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 500° F without degrading.

Square washers fit into slots and channels and have flat sides to keep them from rotating.

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.

These leather washers are nonmarring.

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

18-8 stainless steel spacers have good corrosion resistance.
