Joshua A. ★★★★★

The cadmium finish on these #4-40 screws resisted my clumsy handling without showing a single fingerprint, and the slotted drive cut perfectly into my brass panel without stripping. Exactly the clean look I needed for a restoration project.

Richard ★★★★★

Swapped out some old steel screws for these brass ones on a vintage radio chassis, and the cadmium finish really helps them blend in. The pan head sits flush, and the slotted drive took a standard screwdriver with no camming issues.

Adam B. ★★★★★

The slotted drive on these #4-40 screws fits perfectly with a standard flathead driver, making installation much smoother than I expected. The brass cadmium combo gives them a nice weight and clean look for securing metal brackets on my project. Exactly what I needed for the panel work.
