براغي رأس مقبس M10-1.25 × 80 مم | محرك مقبس سداسي | خيط جزئي | فولاذ سبائك درجة 12.9 أكسيد أسود حراري (50 / عبوة)

Needed M10-1.25 x 80mm screws for a milling fixture, and the hex socket drive made tightening them in tight spots much easier than a traditional head. The black oxide finish also gave them a nice, professional look against the steel plate.

Used these for a custom jig project and the 12.9 alloy steel feels incredibly solid—no stripping at all under heavy torque. The thermal black oxide coating adds a nice, non-glare finish that blends into the machinery well.

Installed these on a CNC fixturing table and the 12.9 alloy steel handled the torque without any distortion. The black oxide finish wiped clean easily even after a day of cutting fluid spray.
