Ellie J. ★★★★★

Finally got around to installing these on a small electronics project and the self-tapping action worked perfectly in thin sheet metal. The flat head sits flush and the Phillips drive didn't cam out once, which is a relief.

Eva E. ★★★★★

I needed tiny stainless screws for a humid outdoor project, and these #4 flat heads are cutting their own threads perfectly into the metal frame. The Phillips drive hasn’t stripped once, even driving a few by hand.

Miles ★★★★★

5000 of them in one box, so this is a buy-once-and-forget situation. The 18-8 stainless gives me confidence they won't rust on the outdoor project I used them for, and the phillips heads seated nicely without stripping.
