Sofia B. ★★★★★

I needed something tougher for my gearbox rebuild, and these 18-8 stainless washers handled the vibration without a hitch. The pack of 250 is exactly what I needed for the project.

Amelia F. ★★★★★

These washers fit perfectly on my 1/2-inch bolts and the 250-count package is a great value for the price. I’ve been using them on a vibration-prone project and they seem to hold tight without loosening. The stainless steel finish is smooth and uniform across every piece.

Jacob ★★★★★

The 18/8 stainless steel finish feels solid, and the 250-count pack means I’ve got plenty for upcoming projects. They gripped tight on a vibrating motor mount I tested, so no loosening after a few days of use.
