Customer Reviews (4.8 / 5 · 5 reviews)

Sofia S. ★★★★★

The partially threaded design worked perfectly for my fixture setup, and the hex socket drive makes tightening them by hand much easier than a standard head. For the price, getting this many quality M3 screws in one pack is a steal.

Hazel ★★★★★

I was a little worried the black oxide finish would rub off during assembly, but it held up perfectly on my jig setup. The partial threading gave just enough grip without binding, and the hex socket drove cleanly with no cam-out.

Isabella A. ★★★★★

These M3-0.5 x 45mm screws worked perfectly for securing jig components on my CNC router. The 12.9 alloy steel feels incredibly strong, and the thermal black oxide finish resists rust well so far.
