Best Washers from Top Stores

Updated October 11, 2026

Compare the best washers from top stores in one place, essential components for bolts and nuts.

Washers on this page are priced from about $0.85 up to $9. They come in steel, brass, bronze, and plastic, with common shapes like flat, dome and spring types.

Pick a washer material that matches the bolt or screw-steel for strength, brass or bronze for corrosion-resistant or decorative uses, and plastic for electrical insulation. Verify the inner diameter fits the fastener’s shank.

Consider the type: flat washers spread load, dome washers add a raised surface, and spring washers provide tension to prevent loosening. Choose the thickness appropriate for the load you expect.

Questions

When should I use a spring washer?

Spring washers are useful where vibration may cause a bolt to loosen.

Are brass washers safe for food-contact applications?

Yes, brass is non-reactive and often used in kitchen hardware.

How do I measure the correct washer size?

Measure the bolt’s shank diameter for the inner hole and the required outer diameter for load distribution.

Can I stack multiple washers?

Stacking can increase load area, but it may affect bolt tension, so do it only when needed.
