Michael ★★★★★

I was replacing some small machine screws and these #4-40 x 3/8" pan heads fit perfectly with the Phillips drive. The black oxide finish looks nice and should resist rust better than plain stainless.

Julian U. ★★★★★

The cone point grabs threads cleanly without stripping, and the black oxide coating’s held up fine during a small electronics bracket install. Pack of 100 means I’ve got spares for the next project, which is always a win.

Ava ★★★★★

The black oxide finish looks sharp and holds up well on my workbench, and the cone point threads started cleanly into the pilot holes without any binding. I grabbed the 100-pack for a small assembly job, and every one of them seated flush with the pan head.
