Edward P. ★★★★★

The black oxide finish on these is uniform and tough—they've held up great in a jig I built with zero rust after a few weeks in the shop. The hex socket drive bites cleanly with a standard Allen key, and the 125mm length is perfect for clamping thicker plates.

Steven C. ★★★★★

The partial threading on these M12 screws made alignment in my jig setup much easier, and the black oxide finish looks clean. They fit the hex socket perfectly with no slop, and the 125mm length was exactly what my tooling needed.

David P. ★★★★★

Used a set to replace worn bolts on a heavy-duty jig, and the 12.9 alloy steel held up perfectly under torque. The partially threaded design made alignment much easier than fully threaded fasteners.
