M12-1.75 X 65mm 外六角螺絲 | 10.9級鋼黃鋅 | 半牙 (50個/包)

Had to replace some worn bolts on a milling machine and these M12s fit perfectly with a socket wrench. The yellow zinc coating and partial threading made installation a breeze.

Used these to bolt down a heavy press at the shop and the partial thread made alignment way easier than a fully threaded bolt would have. The yellow zinc coating still looks clean after a few weeks of oily hands and a little moisture, which is a nice plus.

The hex head grabbed my socket perfectly without any slipping, and the yellow zinc coating looks clean and uniform across all 50 pieces. Used them to bolt down a heavy press stand, and the partial threading made alignment much easier than fully threaded bolts would have.
