M30-3.5 X 110mm 六角頭螺絲 | 10.9級鋼原色 | 部分螺紋 (3件/包)

Bolted these onto a heavy press frame and the thread engagement held rock solid under full torque. The hex head sits flush enough for a socket, and the class 10.9 steel feels dense and tough in hand. Three per pack was exactly what I needed for the job.

The partially threaded design made installation on my large fabrication jig much simpler than I expected. After torquing them down with a heavy duty wrench, they held perfectly without any sign of stripping. These bolts are solid all the way through.

Used these on a heavy press repair and the hex head gave my socket a solid, no-slip grip. The 10.9 grade steel feels reassuringly tough for high-torque applications.
