Missing a few sizes

Mostly complete kit but my box was missing some of the 1/4 inch spring washers. The nuts themselves are good quality though.

Perfect for my workshop

Great assortment of nuts and washers. The separation between 304 and 316 is clearly marked which saves me time on projects.

Good quality steel

Solid nuts and washers. The threads are clean and fit well. Only reason for 4 stars is the latch on the box feels a bit flimsy.

Well organized

The box is sturdy and compartments are sized correctly. Makes finding the right washer very easy during assembly.

316 grade is legit

Used for outdoor railing installation. No signs of rust after several months of exposure to rain. Highly recommend for exterior use.
