M27-3 x 240mm 外六角頭螺絲 | 8.8級鋼原色 | 部分螺紋（3入/包）

I was worried about getting the right torque on these M27-3 bolts, but the hex head fit my wrench perfectly and the partial threads came in handy for aligning the mounting bracket. Solid steel, no give at all—just what I needed for heavy equipment assembly.

The partially threaded design made it easy to get these bolts started by hand before tightening with my impact driver. Seemed like solid class 8.8 steel, and the hex heads held up fine under torque.

The hex heads gave my socket wrench a solid grip without any slipping, and the partial threading made alignment much easier on my press frame. For the price of three bolts, these feel like they'll outlast the equipment I'm fixing.
