About Washers

Metric General Purpose Washers

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

Metric Oversized Washers

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.

Metric Washers for Structural Applications

These thick washers are designed to support structural screws, studs, and nuts.

Metric Plastic Washers

Metric Electrical-Insulating Plastic Washers

Metric High-Temperature Plastic Washers

These metric washers can withstand temperatures up to 450° or 500° F without degrading.

Metal Sealing Washers

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.
