M16-2 x 80mm 六角頭螺絲 | 8.8 級鋼鍍鋅 | 部分螺紋 (25 顆/包)

The partially threaded design makes alignment a breeze when I’m bolting up machinery frames, and the zinc plating’s held up fine so far with no rust after a few weeks in a damp shop. Hex head grips a socket perfectly for torquing down to spec.

These bolts are exactly as specified, class 8.8 with a solid zinc coat, and the partial threading makes them perfect for clamping down a bearing housing. They torqued down cleanly with a socket, which is all I really needed.

Had a stubborn vibration in my press assembly that these M16 bolts fixed perfectly—the partial threading gave just the right grip depth. The hex heads seated well with a standard socket, and the zinc coating seems sturdy enough for a damp shop.
