M18-2.5 X 120mm 六角頭螺絲 | 10.9 級鋼 普通 | 部分螺紋 (25 顆/包)

These M18 hex heads threaded perfectly into our conveyor mounts without any binding. The 10.9 steel feels noticeably tougher than the standard fasteners I've used before.

Tightened these onto a heavy press frame and the 10.9 steel held torque perfectly without any stretch. The partial thread made alignment easy and the hex head grabbed the socket securely.

The partial threading on these M18 hex bolts worked perfectly for clamping a thick flange without bottoming out, and the 10.9 steel held up great under heavy torque. All 25 of them came with clean threads, no burrs to clean up. These are solidly built and worth the money for industrial work.
