Joshua L. ★★★★★

Used them to replace some cheap steel screws on a vintage lamp and the brass finish is exactly the warm, decorative look I wanted. The slotted flat heads sit flush in the countersink and thread easily into wood with just a hand screwdriver. Already ordered another pack for a few more projects.

Lucy Y. ★★★★★

The non-magnetic property was the deciding factor for me, and these haven't let me down in a small electronics enclosure project. The flat heads sit perfectly flush, and the brass finish looks far nicer than plain steel would.

Richard J. ★★★★★

The slotted drive took my flathead screwdriver perfectly without any cam-out issues. These 3-inch brass screws look elegant on my new cabinet pulls and won't rust over time. Exactly the corrosion-resistant, decorative fasteners I needed for this light-duty project.
