Aurora ★★★★★

The brass finish on these #4-40 screws matches my vintage lamp restoration perfectly, and the flat head sits flush without cracking the wood. I’ve used a few so far and they thread smoothly into pre-drilled holes. Great value for a 200-count pack.

Ruby S. ★★★★★

I needed precisely this size for a small jewelry repair and these flat head screws sit flush perfectly. The Phillips drive made installation quick and clean with no stripping.

Samuel ★★★★★

The brass finish is a perfect match for the decorative trim I’ve been working on, and the flat head sits flush without any fuss. The Phillips drive bites well, and the 200-count box means I’ve got plenty left over for future projects.
