These bolts held perfectly when I mounted a heavy jig plate on my mill table, the black oxide finish feels durable and hasn't chipped. The hex socket drive made installation straightforward with an Allen key.

Used these for mounting a heavy steel plate on a press fixture, and the 12.9 alloy steel handled the torque without stripping. The partial threading made alignment easier than full-thread bolts I've used before.

I needed some strong bolts for a jig I was building, and these 12.9 alloy steel screws are definitely up to the task. The black oxide finish gives them a nice, uniform look, and the partial threading made installation a breeze in my project.
