براغي رأس مقبس M8-1 × 60 مم | محرك مقبس سداسي | جزئي الخيوط | سبيكة فولاذ درجة 12.9 أكسيد أسود حراري (100 قطعة/عبوة)

I needed some high-strength fasteners for a jig I'm building, and these M8 socket caps fit the bill perfectly. The 12.9 grade alloy steel feels incredibly sturdy, and the 60mm length was exactly right for my application.

Got these for a jig I was building and the partially threaded design made alignment much easier. The black oxide finish looks solid and they threaded smoothly into pre-tapped holes. Only wish the hex socket was a tad deeper for easier engagement.

The black oxide finish on these screws is really uniform and looks great on my jig setup. The 60mm length was exactly what I needed for a tight assembly, though I wish the bag had a resealable zipper.
