Aurora F. ★★★★★

The box showed up heavier than I expected, which is a good sign for 2,000 pieces. The zinc plating on these #4-40s is nice and even, and the flat undercut head seats flush against my panels without any wobble. They drove in cleanly with a #1 Phillips bit and held tight on the metal brackets I'm repa

Penelope ★★★★★

I was a bit worried about buying such a large pack, but the zinc plating on these screws is really consistent and they drove cleanly into the metal brackets without stripping.

Chloe K. ★★★★★

The undercut head fits perfectly flush into the panel I'm fastening, which saved me from having to countersink each hole. These little screws have great holding power for their size, and the zinc coating looks clean and professional.
