Customer Reviews (4.8 / 5 · 5 reviews)

James ★★★★★

Just got these for a custom tooling project and the black oxide finish looks great — no glare under my shop lights. The button head sits flush enough for tight spaces, and the hex drive grabbed cleanly with no stripping.

Edward O. ★★★★★

Bought these for a small jig build and the hex socket drive let me get them snug in tight spots without stripping. Pack of 2000 is more than I’ll ever need, but the price per screw made it worth it.

Julian A. ★★★★★

I've been swapping out the standard screws on my fixtures with these black oxide button heads and they look sharp while holding tight. The hex socket drive makes them easy to seat without stripping, even in tight spots. For a full box of 2000, the price works out great for shop use.
