M36-4 x 360mm 六角頭螺絲 | 10.9級鋼 無處理 | 部分螺紋 (1 / 包)

Threads are clean and the hex head fits a standard socket without any slop. Used these on a conveyor frame repair and the class 10.9 rating gives me confidence they'll hold up under vibration.

Needed a heavy-duty bolt for a press build, and these M36s didn’t disappoint—the partial threading made alignment a breeze. The hex head grabbed perfectly with a socket, no rounding at all.

The threading stops about halfway down the shaft, which I've found useful for applications where you need a smooth shank to pass through a component. It holds torque well with a wrench, though the price feels a bit steep for just one bolt.
