Customer Reviews (4.6 / 5 · 5 reviews)

Chloe ★★★★★

The Phillips drive on these #4-40 screws catches the driver bit securely, which made installing them into a steel panel much easier than I expected. A full bag of 600 gives you plenty for multiple projects without worrying about running out mid-job.

Robert ★★★★★

The zinc yellow finish on these screws is a nice touch, giving them a bit of corrosion resistance that I was hoping for. Used them to secure a small metal panel and the flat head sat just right. They're exactly what I needed for that job.

Ella F. ★★★★★

The flat head sits perfectly flush in the counterbore on this metal enclosure I'm building, and the phillips drive grabs tight without stripping. For 600 pieces at this price, the zinc yellow finish looks consistent across the whole batch. Just what I needed for a production run of small panels.
