M2-0.4 X 8mm 內六角螺絲 | 六角驅動 | 全螺紋 | 12.9級合金鋼熱處理黑氧化 (600入)

I was worried about stripping such tiny screws, but the hex socket drive engages perfectly and the black oxide coating gives them a nice, uniform look for my jigs.

These little M2 screws are perfect for jig work—the 12.9 alloy steel feels properly tough, and the black oxide finish hasn't shown any wear after a couple of weeks on my bench. A full 600 in the pack means I'll be set for ages, which is exactly what I needed.

The hex socket drive makes it easy to get these M2 screws into tight spots on my jig without stripping. The black oxide finish seems durable and gives them a clean, professional look. Exactly what I needed for precision assemblies.
