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 hold up in blistering temperatures up to 3000° F.

Plastic washers are good electrical insulators.

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.
