M16-2 X 160mm 外六角螺絲 | 10.9級鋼黃鋅 | 部分螺紋 (10 / 包)

Used these to bolt down a heavy press in my shop, and the 10.9 grade steel handled the torque without any flex. The partially threaded shaft made alignment a lot easier than fully threaded bolts would.

The yellow zinc coating looks even better in person and the hex head seated perfectly with my socket wrench on the first try. Threads were clean and the partial threading gave just the right grip for the machinery mount I was bolting down.

I needed M16 fasteners for a heavy steel frame and these 160mm hex heads drove in cleanly with a socket—no stripping or wobble. The yellow zinc finish seems durable enough for shop floor use. Good pack of ten for the price.
