M12-1.5 X 150mm 外六角螺栓 | 10.9級鋼 無處理 | 部分螺紋 (125 / Pkg.)

Used these for securing a heavy press at work and the 10.9 grade held up perfectly under torque. The partial threading made alignment much easier than with fully threaded bolts.

The threading stops exactly where it should, which made seating them in my equipment frame a breeze with a socket wrench. They drove in clean without any binding, and the 10.9 hardness gives me confidence they'll hold up under real load.

Went on easily to replace a broken bolt on a press, and the hex head fit my socket perfectly. The partially threaded design was exactly what I needed for even clamping force.
