Excellent quality brass

These screws are exactly what I needed for my vintage lamp restoration. The brass is thick and doesn't strip easily like cheaper zinc-plated versions. The washers fit perfectly.

Good variety pack

Great assortment of sizes for general household repairs. The only reason for 4 stars instead of 5 is that I wished there were slightly more of the medium-sized screws in the kit.

Perfect for marine projects

I used these on a small boat repair project near the coast. After three months of exposure to salt air, there is absolutely no sign of rust or corrosion. Highly recommended.

Solid hardware

As an electrician, I go through a lot of connectors. These brass screws provide excellent conductivity and the cross-head design grips the screwdriver well.

Beautiful finish

The gold tone of the pure brass looks very premium on my wooden jewelry box. They tightened smoothly without snapping. Will definitely buy again.

Exactly as described

Fast shipping and the packaging kept everything organized. The inclusion of both flat and spring washers saved me a trip to the hardware store.
