M14-2 X 180mm 六角頭螺絲 | 10.9級鋼鍍鋅 | 部分螺紋 (75/包)

Finally a bolt that doesn’t strip when I torque it down for a machine base assembly—the hex head grips perfectly with a socket. The zinc plating seems decent so far, no rust after a week in a damp workshop.

Installed these on a heavy-duty jig I'm building, and the 180mm length with partial threading gave me just the right grip depth for a solid hold. The zinc coating looks clean and should resist rust well.

The 75-count package saved me a trip to the hardware store, and the partial threading made alignment much easier on my assembly jig. These M14 bolts held up perfectly under torque—no stripping or bending.
