Customer Reviews (4.8 / 5 · 5 reviews)

Madison Q. ★★★★★

Putting in these little screws was surprisingly satisfying — the flat head sits perfectly flush in my plywood jigs every time. For 1,200 pieces at this price, it's hard to beat the value for indoor projects.

Edward S. ★★★★★

These flat heads sit flush without needing to countersink, which saved me a ton of time on a jig build. They drive in smooth with just a standard Phillips bit.

James ★★★★★

The bag of 1,200 is a solid deal for shop stock, and the Phillips drive bites well without stripping on these flat heads. Plain steel is fine for my indoor jigs, just keep them out of any damp spots.
