Avery B. ★★★★★

These were the exact size I needed for a small electronics enclosure I was repairing, and the zinc yellow finish matches the original hardware perfectly. The slotted drive is classic and works fine with a standard screwdriver.

Elizabeth ★★★★★

Had to replace some old screws on a metal enclosure and these fit perfectly with a standard slotted driver. The threads are clean and catch right away without any binding.

Daniel Y. ★★★★★

The zinc yellow coating on these #5-40s is holding up well on my steel panel enclosures, no rust after a few weeks. Fit perfectly into tapped holes without any stripping. Exactly what I needed for a clean fastening job.
