About Washers

General Purpose 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.

Oversized Washers

Compared to our general purpose washers, these have exaggerated diameters and/or thicknesses for covering oversized holes or for use as spacers and levelers.

Metric Oversized Washers
