M2-0.4 x 10mm 內六角螺絲 | 平頭內六角驅動 | 全螺紋 | 10.9級合金鋼熱處理黑色氧化 (400顆/包)

The hex socket drive on these M2 screws makes installation a breeze with precision tools on my jig setup. The black oxide finish feels sturdy and the threads are perfectly clean right out of the package.

I use these M2 screws for securing small jig components on my CNC router and they seat perfectly with a 1.5mm hex driver. The 10.9 grade alloy steel feels solid and the threads are clean, no binding at all across the whole pack.

The black oxide finish on these M2 screws is what sold me—they fit neatly into my precision fixture without any galling, and the 10.9 alloy steel feels rock solid. Pack of 400 means I won't run out mid-project, which is exactly what I needed.
