M30-3.5 x 340mm 六角頭螺絲 | 10.9級鋼製無處理 | 部分螺紋 (1顆/包)

The hex head on these M30 screws gave my socket wrench a solid grip, and the partially threaded section made alignment much easier during assembly. They feel tough enough for heavy machinery work.

The partially threaded design made these M30 screws perfect for the specific depth I needed in my press setup. The hex head gripped my socket wrench firmly without any slipping during final tightening.

Installed these on a piece of heavy equipment yesterday and the hex head gave my torque wrench a solid grip without any slipping. The 340mm length and partial threading made alignment much easier than I expected for such a large bolt.
