M12-1.25 X 80mm 六角頭螺絲 | Class 10.9 鋼黃鋅 | 部分螺紋 (50入/包)

The partial threading is perfect for clamping down on thick flanges without stripping, and the yellow zinc coating held up fine during a rainy weekend install.

Needed a handful of these for a heavy machinery repair, and the 10.9 grade steel handled the torque without any issues. The zinc coating gives them a nice consistent look, and the hex heads fit a socket wrench perfectly.
