Customer Reviews (4.4 / 5 · 5 reviews)

Claire ★★★★★

I was skeptical about the hex socket drive at first, but it holds torque much better than a Philips on my jig. The black oxide finish seems durable and hasn't shown any rust after a week in the shop.

Benjamin M. ★★★★★

The black oxide finish on these M5 screws looks clean and professional on my jig setup. The 55mm length was exactly what I needed for clamping thicker workpieces. They drove in smoothly with no stripping.

Violet N. ★★★★★

I needed longer M5 screws for a custom jig build, and these 55mm ones fit perfectly. The black oxide finish feels solid and looks clean against my aluminum frame.
