Customer Reviews (4.8 / 5 · 5 reviews)

Owen N. ★★★★★

The black oxide finish on these M5 screws looks great and gives them a professional, durable feel far beyond standard hardware. I’m using them for jig assembly and they seat cleanly with no wobble.

Victoria ★★★★★

Installed these in a jig I’m building, and the black oxide coating gives a nice consistent finish. The 10.9 grade feels sturdy under torque without any stripping.

Ruby X. ★★★★★

The hex socket drive on these M5 screws gives a really solid grip, and the black oxide finish looks clean for jig work. I’ve used a handful so far, and they thread smoothly into aluminum without stripping. Exactly what I needed for my precision assembly projects.
