Richard ★★★★★

I've been using these M5 x 45mm screws for a jig I'm building, and they thread in smoothly every time — the hex socket drives cleanly without any stripping at 12.9 grade strength. The black oxide coating feels dry to the touch, which makes them easy to handle even with oily fingers.

Abigail S. ★★★★★

The black oxide finish on these 12.9 alloy screws holds up nicely in my drill jig without any rust after a week of coolant exposure. They seat deep with the hex drive, which is a solid improvement over the cheap zinc ones I was using before.

Aurora ★★★★★

Third order of these for a custom jig setup, and the 12.9 alloy steel has never snapped on me yet. The 45mm length is exactly right for sandwiching thicker brackets, and the black oxide finish makes them look clean in the tool cabinet.
