M10-1.5 X 260mm 內六角螺絲 | 六角驅動 | 半牙 | 12.9級合金鋼熱處理黑化 (25 / 包)

I needed some longer cap screws for a custom jig build and these 260mm ones fit the bill perfectly. The hex socket drive gave a solid grip with my allen key, and the partial threading made alignment against the workpiece easy.

The black oxide finish on these M10s is exactly what I needed for a jig setup—no reflection issues under bright shop lights. The 12.9 alloy steel feels dense and solid in the hand, and the partial threading seated cleanly into my fixture without binding.

Installed a few in a machine tool fixture, and the 260mm length gave me exactly the reach I needed. The black oxide finish looks durable and the hex drive seated cleanly without any stripping.
