5-Pack 5/8" Conical Belleville Spring Washers – A2 Stainless Steel – 18-8 Grade

These are heavy-duty Belleville washers, also called conical or cupped washers.

You get a pack of five, each with a 5/8-inch hole size.

They're made from A2 stainless steel, 18-8 grade, so they're rust-resistant and strong.

They measure about .673 inches in outer diameter and 5/32 inches thick.

These are perfect for applications where you need a spring-like tension or want to compensate for thermal expansion.

Whether you're working on machinery, automotive, or just need some heavy-duty lock washers, these will do the job.
