Customer Reviews (5.0 / 5 · 5 reviews)

Harper ★★★★★

The flat head sits perfectly flush in the panel, and the Phillips drive grabs the bit without any cam-out. These are exactly the right size for the metal enclosure I was repairing.

Andrew C. ★★★★★

I needed 316 stainless for a saltwater environment and these flat-head #4-40s fit perfectly into my enclosure holes. The phillips drive didn’t cam out even with a power driver, which was a nice surprise for screws this tiny.

Owen ★★★★★

Finally, a batch of tiny screws where every single one has a clean, deep phillips slot — no stripping right out of the box. The 316 stainless feels reassuringly heavy for its size, and the flat head sits flush in our panel enclosures.
