Customer Reviews (4.4 / 5 · 5 reviews)

Chloe ★★★★★

The brass finish looks great on my antique-style drawer pulls, and the flat head sits flush without any sanding. These are non-magnetic too, which mattered for my electronics project.

George T. ★★★★★

Used these for a small jewelry repair project, and the brass heads look much nicer than steel alternatives. The Phillips drive bit seated cleanly without stripping, even on the 3/4" length. Exactly what I needed for a light-duty decorative fastening job.

Sophia ★★★★★

These are perfect for a small electronics project I was working on; the flat heads sit flush against the panel. The brass finish looks much nicer than standard steel, and the 200-count pack means I have plenty of spares.
