M10-1.5 X 12mm 六角穴付きキャップスクリュー | 六角穴ドライブ | 全ねじ | 12.9級 合金鋼 黒色酸化被膜 (200本/袋)

The black oxide finish on these screws looks great and seems to hold up well during assembly work. I used them on a jig fixture and the hex socket drove cleanly without any cam-out. Exactly the thread pitch I needed for M10 fastening.

I needed some high-strength fasteners for a jig I’m building, and these black oxide M10 screws look the part. The 12.9 alloy steel feels really solid, and the recessed hex drive seated cleanly without stripping.

The hex socket drive seated perfectly without any stripping, even torquing them down into a steel jig plate. I appreciate the consistent threading across the whole batch, and the black oxide finish gives them a nice, durable look for tooling.
