What is a USAE Washer?

It is a simple but effective idea that is long overdue.

The OD conforms to USS standards. This provides a washer that is up to 36% larger than standard hardened washers.

MORE CONTACT AREA = MORE HOLDING POWER

The ID conforms to SAE standards. The small ID provides a more precise fit on bolts, studs, etc.

USAE Washers are also up to 37% thicker than standard hardened washers for greater strength.

Washers are made from mild steel. They are case hardened and have a black oxide finish. Shipped in plain boxes.

Bolt size is stamped on the washer for easy identification.

Compare the USAE Washer to what you currently use.
