Daniel R. ★★★★★

I needed a bulk supply of these for jigs and fixtures, and the slotted drive makes them easy to tighten by hand when I'm adjusting a setup. The plain steel finish is fine for my indoor shop, and the flat head countersinks cleanly.

Stella L. ★★★★★

The heads sit perfectly flush in my countersunk holes, which is exactly what I needed for this shelf. Plenty of bite with the slotted drive, and the plain steel is fine since it's all indoors anyway.

Avery B. ★★★★★

I needed a bulk set for a workbench project and these flat head screws countersink perfectly flush. The slotted drive feels old-school but it works fine, and the plain steel holds up well indoors.
