M12-1.75 X 50mm ソケットキャップスクリュー | フラットヘッド六角ソケットドライブ | 全ねじ | 10.9級合金鋼熱処理黒色酸化 (100個/パック)

These M12 socket cap screws were exactly what I needed for a new jig I’ve been building, and the hex drive made tightening them down in tight spots really easy. The fully threaded length gives a solid, secure hold, and the black oxide finish looks clean against the metal.

Black oxide finish is holding up nicely on my jig fixtures after a few weeks of regular use, and the hex socket drive seated every screw without stripping. Class 10.9 strength gives me confidence these won’t fatigue in the tooling setup.

I mounted these to replace worn bolts on a press fixture, and the Class 10.9 strength held up perfectly under heavy load. The black oxide finish gave them a clean look too, no complaints.
