Customer Reviews (4.4 / 5 · 5 reviews)

Lucy C. ★★★★★

I was pleasantly surprised at how precise the hex socket drive is on these tiny screws—fit my tool perfectly without any stripping. For small jig work, the class 12.9 alloy steel feels reassuringly tough.

David R. ★★★★★

I needed some small precision fasteners for a jig I’m building, and these M2.5 screws fit perfectly. The hex socket drive makes them easy to install in tight spots, and the black oxide finish looks clean.

Lily ★★★★★

These M2.5 button heads are exactly what I needed for a small jig I was building, and the black oxide finish looks great against the aluminum. The hex socket drive made installation much smoother than dealing with a standard slot.
