M30-3.5 X 320mm 六角頭螺絲 | 10.9 級鋼 無鍍層 | 部分螺紋 (1 入)

The partial threading made alignment in tight spots much easier than I expected, and the 10.9 steel feels rock solid under load. These M30 bolts handled my equipment frame without any flex.

The hex head gave my wrench a solid grip right from the start, and the partial threading made alignment a breeze. These Class 10.9 bolts feel tough enough to handle heavy machinery without flexing.

The threading is smooth and precise—no binding when I tightened it into the mount on my press. The hex head grips the socket perfectly, making installation straightforward with just a wrench. Exactly the heavy-duty fastener I needed for this industrial job.
