Customer Reviews (5.0 / 5 · 5 reviews)

Sofia ★★★★★

The flat head sits flush against the panel perfectly, and the 18/8 stainless steel feels solid and corrosion-resistant. I used a handful to secure a small electronics enclosure, and the nylon patch held them tight against vibration.

Samuel I. ★★★★★

The nylon patch on these #4-40 screws holds them snugly in place once threaded into an enclosure, which is exactly what I needed for a vibration-prone panel. The flat head sits flush and the 18/8 stainless finish looks clean. Pack of 100 is plenty for a few small projects.

Jacob G. ★★★★★

Used a full pack for mounting a control panel bracket and every screw seated flush without stripping. The flat head countersinks cleanly and the 18/8 stainless gives confidence they won't rust in a slightly damp shop.
