Victoria R. ★★★★★

I needed some small screws for a jig I was building, and these #4-40 button heads went in smoothly without stripping. The black oxide finish looks clean and should hold up well on the shop floor.

Sophia K. ★★★★★

These button heads fit perfectly into my jig’s recessed holes, and the black oxide coating gives them a nice, consistent finish. The hex socket drive made installation smooth with a standard driver.

Emily P. ★★★★★

Was looking for a sturdy fastener for a jig I'm building, and the black oxide finish on these #4-40 screws is holding up well against minor scrapes. The hex socket drive makes tightening them in tight spots a breeze.
