M12-1.25 X 140mm 六角頭帽螺絲 | 等級 10.9 鋼 普通 | 部分螺紋 (125 / 包)

I needed long bolts for a structural frame, and these M12-1.25 x 140mm screws with partial threading made alignment much easier during assembly. The 10.9 grade steel feels rock solid under torque.

The partial threading on these bolts made it much easier to get a clean fit through thick steel brackets, and the hex head gripped perfectly with a standard socket wrench. Great quality for the price, especially for heavy equipment assembly.

Used these to bolt down a heavy machine base at work and the class 10.9 steel handled the torque without a hint of flex. Nice that they come in a 125-piece box, so I've got plenty left over for the next job.
