Great variety of sizes

The assortment kit covers almost every size I use in my workshop. The M4 and M6 sizes are my most used, and they fit perfectly. Deducting one star because the packaging was slightly damaged upon arrival.

Excellent quality steel

These washers are exactly what I needed for my automotive project. The 304 stainless steel is thick and durable, not flimsy like cheaper alternatives.

True anti-loose performance

I installed these on a vibrating motor assembly, and they have held up perfectly without loosening over three months of continuous operation.

Perfect for outdoor projects

Used these for a garden fence installation. Since they are 304 stainless, I don't have to worry about rust even with exposure to rain and soil.

Professional grade

As a professional mechanic, I go through a lot of hardware. These washers meet industry standards and the finish is consistent across all sizes.

Good value for money

Solid washers at a reasonable price. The thickened design provides good tension. I wish the M10 count in the pack was slightly higher.
