M20-2.5 X 70mm 六角頭螺栓 | 10.9 級鋼 鍍鋅 | 全牙 (25 顆/包)

Used these for mounting a heavy steel bracket on a machine base, and the fully threaded shaft let me dial in the exact depth I needed. The zinc plating still looks clean after a week of dusty shop use.

The hex head on these M20 bolts grips the socket perfectly without slipping, which makes torquing them down much easier. They're fully threaded so I got good bite even with a thick steel bracket I was mounting. Solid fasteners for the price, no complaints at all.

The threads are clean and the zinc plating looks uniform, so no binding when I drove them into tapped holes. Used a dozen on a press frame and the Class 10.9 rating gives me confidence they'll hold torque without stretching.
