M16-2 X 180mm 六角頭螺絲 | 強度10.9 鋼 無處理 | 部分螺紋 (5入/包)

The hex head on these screws is a perfect fit for my socket, and the 180mm length worked great for bolting down some heavy equipment. These are solid, well-made fasteners that feel like they'll handle serious torque without stripping.

Installed these on a steel frame assembly and the 10.9 grade held up perfectly under torque. The partial threading made alignment much easier than expected.

Needed these for a heavy equipment jig I'm building, and the 180mm length was exactly right. The hex head grabbed my socket cleanly and the 10.9 steel feels like it'll handle the torque without stripping.
