M6-1 X 60mm 六角頭螺栓 | 10.9 級鋼鍍鋅 | 全螺紋 (1200 個/包)

These are exactly what we needed for some heavy-duty assembly work. The hex head fits a standard 10mm socket perfectly, making them easy to drive in tight spots without stripping.

I was a bit skeptical about getting a full box of these, but the consistent quality across all 1200 pieces really impressed me. The zinc plating looks even and smooth, and the wrench grip on the hex head is solid.

Finally, a batch of M6 bolts where every single one threads cleanly into a tapped hole without binding. The zinc plating is uniform and gives them a nice, consistent look for exposed fasteners on my jig.
