Customer Reviews (4.8 / 5 · 5 reviews)

Christopher ★★★★★

Red patch holds tight without any extra locking compound—I've been using them for mounting brackets inside electrical panels. The 18/8 stainless finish cleans off easily if I get grease on them during assembly.

Eli J. ★★★★★

Finally found the right screw for a custom panel project I've been working on—the 18/8 stainless steel feels solid and should resist corrosion well. The #4-40 x 1" size fit perfectly into the threaded holes on my aluminum enclosure, and the pan head sits flush without interfering with the cover.

Grace ★★★★★

For years I've struggled with low-quality screws that strip easily, but these pan head ones hold firmly with just a Phillips driver. The 18/8 stainless steel feels dense and solid, and having a full 2000-count package means I won't run out mid-project.
