M12-1.75 X 25mm 六角頭螺絲 | 10.9級鋼鍍鋅 | 全螺紋 (150 / 包)

The zinc plating on these M12 bolts looks clean and even, so they should resist rust well in my shop equipment. They threaded into the tapped holes smoothly without any binding, which is exactly what you want for precise assembly.

Installed these on a small jig I was building, and the fully threaded shaft made alignment a breeze. The zinc plating looks consistent and clean.

Finally, a machine bolt that doesn't strip under torque—these 10.9 grade hex heads held firm when I tightened them on a conveyor frame. The zinc coating gives them a clean, uniform look, and having 150 in the box means I won't run out mid-project.
