M12-1.75 x 110mm 六角頭螺絲 | 等級10.9 鋼 黃鋅 | 部分螺紋 (25 / 包)

The partially threaded design made torquing these down in an equipment jig much easier than fully threaded bolts would have been. Threads ran cleanly into the tapped holes without any binding, and the hex head gave a perfect socket fit. These feel solid for heavy-duty assembly work.

The yellow zinc coating is way brighter in person than the photos suggested, which is nice for when these are visible on the equipment. The 110mm length with the partial thread gave me just the right grip when securing a heavy mounting plate. They torqued down smoothly without any galling on the thr

Installing these on a conveyor frame and the hex head lets me really torque them down without cam-out. The yellow zinc finish looks clean and the partial threading makes alignment quick.
