Professional grade

As a furniture maker, I go through a lot of fasteners. These meet the national standard perfectly and the spring washers provide excellent tension. Highly recommended for pros.

Beautiful finish

Used these for a custom jewelry box. The gold tone of the brass looks very elegant against the walnut wood. They sit perfectly flush due to the countersunk design.

Good value set

Great assortment of sizes. The only reason I didn't give 5 stars is that the box labeling could be clearer regarding the specific thread pitch, but the quality of the metal is top-notch.

Solid purchase

Very happy with this set. The nuts thread smoothly onto the screws without any binding. It's a comprehensive kit that covers most of my household repair needs.

Perfect for marine projects

I used these on a small boat repair project. Since they are pure brass, I don't have to worry about rust in the saltwater environment. The fit is precise and the cross head grips well.

Excellent quality brass hardware

These screws are exactly what I needed for my vintage radio restoration. The brass is thick and doesn't strip easily. Having the washers and nuts included saved me a trip to the hardware store.
