Matthew ★★★★★

I was replacing some old decorative brackets on a jewelry box and these brass screws matched perfectly — the corrosion resistance is a nice bonus for anything that might get occasional moisture exposure. Binding head sits flush without catching on fabric, which saved me having to countersink.

Ruby ★★★★★

Slot drive on these #4-40s is nicely cut, so a standard screwdriver bites without slipping. The brass finish looks clean for the small decorative joints I used them on, and the 3/8" length was just right.

Aurora J. ★★★★★

Needed a bunch of small brass screws for a model ship project, and these #4-40s have just the right weight and shine. The binding heads give a neat, low-profile finish that looks much better than regular pan heads.
