Customer Reviews (4.8 / 5 · 5 reviews)

Emma ★★★★★

The black oxide finish on these screws is consistent and clean, and they fit perfectly into my jig with no wobble. For just over 40 cents a piece, the 12.9 alloy steel feels like a solid upgrade over standard hardware.

Julian ★★★★★

These are exactly what I needed for a jig I’m building—the hex socket drive makes tightening them in tight spots easy. The flat head sits flush in counterbored holes, which is great for a clean assembly.

Henry ★★★★★

The black oxide finish on these screws is a nice touch—no glare under workshop lights, and they thread smoothly into tapped holes. I used them for a jig build and every single screw seated cleanly with no wobble. For the price per piece, this pack is a solid deal for anyone doing precision work.
