Customer Reviews (4.4 / 5 · 5 reviews)

Adam ★★★★★

These are holding up great on my jig fixtures after a month of heavy use, and the black oxide finish hasn't chipped at all. The 12.9 grade steel gives me confidence they won't snap under torque.

Claire ★★★★★

The black oxide finish on these screws is holding up great in my shop jig setup without any rust. They threaded smoothly into pre-tapped holes and the hex socket seated perfectly with no stripping. Definitely a solid batch for precision assembly work.

Ryan ★★★★★

Finally found some M8 button heads that fit perfectly into my jig's counterbored holes without sticking up. The black oxide finish cleaned off easily with a little alcohol, and every one of the 200 screws threaded smoothly into my aluminum fixtures.
