M8-1.25 x 12mm 內六角螺絲 | 平頭內六角驅動 | 全牙 | 12.9級合金鋼鍍鋅 (300個/包)

The zinc plating is holding up well in my jig setup, no rust after a few weeks in a damp shop. Exactly 12mm long as advertised, and the hex drive spins in clean without stripping.

The hex socket drive on these M8 screws made tightening them in my jig setup much easier than using a standard hex key. All 300 pieces in the package were uniformly threaded and the zinc plating looks clean and durable. Just what I needed for a solid machinery assembly.

These are exactly the right length for jig work; the hex socket engages cleanly even after a few uses. Took them out of the package and they threaded smoothly into the tapped holes with zero binding.
