M10-1.5 X 170mm 六角頭螺絲 | 10.9級鋼 原色 | 部分螺紋 (20顆/包)

I needed some heavy-duty bolts for a press jig, and these 170mm long screws had the reach and grip I needed. The hex head held up perfectly to high torque with a socket wrench.

Finally, a bolt long enough for my heavy equipment jig without having to weld two together. The 10.9 grade steel handled the torque on the first test run perfectly.

The partially threaded design made these perfect for the machinery assembly I was working on. They're solidly built and the 170mm length was exactly what I needed, though the finish could be a bit cleaner.
