Grade 8 SAE Flat Washers

Grade 8 SAE flat washers are heat-treated alloy steel washers in the close-fitting SAE pattern. They hold their shape under the high clamp load of Grade 8 bolts, so the joint keeps its tension. They are the standard choice for automotive, suspension and machinery work with Grade 8 fasteners. They come yellow zinc plated from 1/4" through 1-1/2", and there is a 468 piece Grade 8 washer assortment.

FAQ

Can I use Grade 8 washers with Grade 5 bolts?
Yes. A hardened washer works with any lower grade bolt. The reverse, a soft washer under a Grade 8 bolt, is what to avoid.

Is a #8 washer the same as a Grade 8 washer?
No. A #8 washer is a small size that fits a #8 screw. Grade 8 is a strength rating for washers sized 1/4" and up.
