Edward ★★★★★

I needed tiny screws for a metal enclosure project, and these 18/8 stainless steel pan heads fit perfectly with no rust worries. The 100-count pack is great value, and every screw I’ve used so far has threaded smoothly without jamming.

Eli ★★★★★

The Phillips drive on these #4-40 screws grabbed my driver perfectly without any cam-out, and the 18/8 stainless steel has a clean, consistent finish. They worked great for securing a small metal enclosure panel.

Olivia T. ★★★★★

I was replacing some old screws on a metal enclosure, and these #4-40s threaded in smoothly without stripping. The 18/8 stainless steel feels solid and corrosion-resistant for outdoor use.
