M6-1 X 120mm 六角頭螺絲 | 10.9 級鋼鋅鍍 | 部分螺紋 (100 入/包)

I needed some long M6 bolts for a heavy assembly jig, and the 120mm length with partial threading made alignment much easier. The zinc coating looks clean and the class 10.9 rating gives me confidence they won't shear under load. Pack came with exactly 100, all threads were clean.

These are perfect for bolting down some heavy equipment I’ve been working on; the partial threads make alignment much easier, and the zinc coating seems good and even.

The hex head design gave my socket wrench a solid grip without slipping, and the zinc plating looks clean enough to not rust in my damp workshop. These 120mm screws held a heavy bracket securely with the partial thread biting perfectly.
