M8-1.25 X 8mm 內六角螺絲 | 內六角驅動 | 全牙 | 12.9級合金鋼鍍鋅 (100顆/包)

I needed something tough for a jig I was building, and these M8 socket cap screws held up perfectly under pressure. The hex drive seated cleanly without any stripping, and the zinc plating gives them a nice, uniform look.

Finally, a cap screw that fits exactly in my jig’s counterbore without any slop. The hex drive is clean and doesn’t strip under 12.9 grade torque.

Pulling these out of the package, the zinc plating looks uniform and clean, which gives me confidence they won't rust in my jig setup. The hex socket drive engaged perfectly with my Allen key, and the full threading along the entire 8mm length made them easy to tighten down in tight spots.
