M16-2 x 120mm 六角頭螺絲 | 鋼材 10.9 級鍍鋅 | 部分螺紋 (25 入/包)

The hex head made it easy to get a socket on these for tightening down a conveyor roller bracket. The partial threading helped them seat cleanly without binding in the blind hole. Solid feel for the price.

Got these to replace bolts on a piece of agricultural equipment, and the 10.9 grade held up great under heavy torque. The zinc plating seems solid too, no rust after a few days in damp conditions.

Worked perfectly for mounting a heavy motor mount where the partial thread gave just enough grip without bottoming out. The zinc coating looks clean and uniform, and they torqued down solidly without any issues.
